Assembling Objects

15 questions · 18 min on the real test
Question 1 · AO · easy

The left box shows separate flat pieces. Which figure shows how the pieces look when they are fitted together?

Left box: 2 separate flat pieces: a five-sided piece (about 51% of the total area), a five-sided piece (about 49% of the total area).
Show the answer

Answer: A

Count the pieces first: every figure must use each piece exactly once, with nothing added. Then pick one distinctive piece, such as the largest one or one with a curved or sharply pointed edge, and look for it in each figure; pieces may be turned but never flipped over. A figure whose cut lines are in different places has pieces of different sizes and can be crossed out. Here the pieces fit together into a hexagon.

  • A (correct): This hexagon is made of exactly the 2 pieces in the left box, each only turned and slid into place.
  • B: A cut is in a different place, so the pieces do not match: one piece here covers about 18% of the shape, but the matching piece in the left box covers about 49%.
  • C: This figure has 3 pieces, but the left box has 2. Every piece must be used once, and nothing may be added.
  • D: This figure is a circle. The pieces in the left box do not have these shapes, so they cannot fill this outline without gaps or overlaps.
Question 2 · AO · easy

The left box shows separate flat pieces. Which figure shows how the pieces look when they are fitted together?

Left box: 2 separate flat pieces: a five-sided piece (about 80% of the total area), a triangle (about 20% of the total area).
Show the answer

Answer: D

Count the pieces first: every figure must use each piece exactly once, with nothing added. Then pick one distinctive piece, such as the largest one or one with a curved or sharply pointed edge, and look for it in each figure; pieces may be turned but never flipped over. A figure whose cut lines are in different places has pieces of different sizes and can be crossed out. Here the pieces fit together into a parallelogram.

  • A: This figure is a rectangle. The pieces in the left box do not have these shapes, so they cannot fill this outline without gaps or overlaps.
  • B: This figure has 3 pieces, but the left box has 2. Every piece must be used once, and nothing may be added.
  • C: A cut is in a different place, so the pieces do not match: one piece here covers about 48% of the shape, but the matching piece in the left box covers about 20%.
  • D (correct): This parallelogram is made of exactly the 2 pieces in the left box, each only turned and slid into place.
Question 3 · AO · easy

The left box shows two shapes, each with a lettered point, and a line with the same two letters on its ends. Which figure shows how the shapes connect when each end of the line is attached to the point with the same letter?

Left box: a house shape with point G at the peak of the roof, a parallelogram with point H at the middle of a short side, and a separate line with end G and end H.
Show the answer

Answer: D

Check one letter at a time. Point G is at the peak of the roof of the house shape, and point H is at the middle of a short side of the parallelogram. Cross out any figure where either end of the line lands somewhere else or where a shape has changed. The shapes may be turned, so find each point by its place on the shape (corner, middle of a side, center), not by up, down, left or right.

  • A: The line ends in the wrong place: it meets the house shape at the middle of a wall, but point G is at the peak of the roof and it meets the parallelogram at a sharp corner, but point H is at the middle of a short side.
  • B: The line ends in the wrong place: it meets the house shape at a bottom corner, but point G is at the peak of the roof.
  • C: The line ends in the wrong place: it meets the house shape at the middle of the bottom side, but point G is at the peak of the roof.
  • D (correct): The line joins the peak of the roof of the house shape to the middle of a short side of the parallelogram, the same spots as points G and H in the left box; turning a shape does not move a point on it.
Question 4 · AO · easy

The left box shows two shapes, each with a lettered point, and a line with the same two letters on its ends. Which figure shows how the shapes connect when each end of the line is attached to the point with the same letter?

Left box: a square with point X at a corner, a right triangle with point Y at the sharpest corner, and a separate line with end X and end Y.
Show the answer

Answer: C

Check one letter at a time. Point X is at a corner of the square, and point Y is at the sharpest corner of the right triangle. Cross out any figure where either end of the line lands somewhere else or where a shape has changed. The shapes may be turned, so find each point by its place on the shape (corner, middle of a side, center), not by up, down, left or right.

  • A: The line ends in the wrong place: it meets the square at the middle of a side, but point X is at a corner and it meets the right triangle at the middle of the longer leg, but point Y is at the sharpest corner.
  • B: The line ends in the wrong place: it meets the right triangle at the middle of the slanted side, but point Y is at the sharpest corner.
  • C (correct): The line joins a corner of the square to the sharpest corner of the right triangle, the same spots as points X and Y in the left box; turning a shape does not move a point on it.
  • D: The line ends in the wrong place: it meets the right triangle at the middle of the shorter leg, but point Y is at the sharpest corner.
Question 5 · AO · medium

The left box shows two shapes, each with a lettered point, and a line with the same two letters on its ends. Which figure shows how the shapes connect when each end of the line is attached to the point with the same letter?

Left box: a right triangle with point E at the right-angle corner, a triangle with point F at a corner, and a separate line with end E and end F.
Show the answer

Answer: D

Check one letter at a time. Point E is at the right-angle corner of the right triangle, and point F is at a corner of the triangle. Cross out any figure where either end of the line lands somewhere else or where a shape has changed. The shapes may be turned, so find each point by its place on the shape (corner, middle of a side, center), not by up, down, left or right.

  • A: The line ends in the wrong place: it meets the right triangle at the sharpest corner, but point E is at the right-angle corner.
  • B: The line ends in the wrong place: it meets the right triangle at the middle of the shorter leg, but point E is at the right-angle corner.
  • C: The line ends in the wrong place: it meets the right triangle at the middle of the slanted side, but point E is at the right-angle corner and it meets the triangle at the middle of a side, but point F is at a corner.
  • D (correct): The line joins the right-angle corner of the right triangle to a corner of the triangle, the same spots as points E and F in the left box; turning a shape does not move a point on it.
Question 6 · AO · medium

The left box shows separate flat pieces. Which figure shows how the pieces look when they are fitted together?

Left box: 3 separate flat pieces: a five-sided piece (about 47% of the total area), a four-sided piece (about 29% of the total area), a four-sided piece (about 24% of the total area).
Show the answer

Answer: C

Count the pieces first: every figure must use each piece exactly once, with nothing added. Then pick one distinctive piece, such as the largest one or one with a curved or sharply pointed edge, and look for it in each figure; pieces may be turned but never flipped over. A figure whose cut lines are in different places has pieces of different sizes and can be crossed out. Here the pieces fit together into a pentagon.

  • A: A cut is in a different place, so the pieces do not match: one piece here covers about 38% of the shape, but the matching piece in the left box covers about 47%.
  • B: This figure has 4 pieces, but the left box has 3. Every piece must be used once, and nothing may be added.
  • C (correct): This pentagon is made of exactly the 3 pieces in the left box, each only turned and slid into place.
  • D: This figure is a hexagon. The pieces in the left box do not have these shapes, so they cannot fill this outline without gaps or overlaps.
Question 7 · AO · medium

The left box shows two shapes, each with a lettered point, and a line with the same two letters on its ends. Which figure shows how the shapes connect when each end of the line is attached to the point with the same letter?

Left box: a half-circle with point G at the top of the curved side, a house shape with point H at the peak of the roof, and a separate line with end G and end H.
Show the answer

Answer: D

Check one letter at a time. Point G is at the top of the curved side of the half-circle, and point H is at the peak of the roof of the house shape. Cross out any figure where either end of the line lands somewhere else or where a shape has changed. The shapes may be turned, so find each point by its place on the shape (corner, middle of a side, center), not by up, down, left or right.

  • A: The line ends in the wrong place: it meets the half-circle at a corner of the flat side, but point G is at the top of the curved side.
  • B: The line ends in the wrong place: it meets the house shape at the middle of the bottom side, but point H is at the peak of the roof.
  • C: The line ends in the wrong place: it meets the half-circle at the middle of the flat side, but point G is at the top of the curved side.
  • D (correct): The line joins the top of the curved side of the half-circle to the peak of the roof of the house shape, the same spots as points G and H in the left box; turning a shape does not move a point on it.
Question 8 · AO · medium

The left box shows two shapes, each with a lettered point, and a line with the same two letters on its ends. Which figure shows how the shapes connect when each end of the line is attached to the point with the same letter?

Left box: a half-circle with point P at a corner of the flat side, a rectangle with point Q at the center, and a separate line with end P and end Q.
Show the answer

Answer: A

Check one letter at a time. Point P is at a corner of the flat side of the half-circle, and point Q is at the center of the rectangle. Cross out any figure where either end of the line lands somewhere else or where a shape has changed. The shapes may be turned, so find each point by its place on the shape (corner, middle of a side, center), not by up, down, left or right.

  • A (correct): The line joins a corner of the flat side of the half-circle to the center of the rectangle, the same spots as points P and Q in the left box; turning a shape does not move a point on it.
  • B: The line ends in the wrong place: it meets the rectangle at the middle of a long side, but point Q is at the center.
  • C: One of the shapes here is a square, but the left box has a rectangle. Joining parts never changes a shape.
  • D: The line ends in the wrong place: it meets the half-circle at the top of the curved side, but point P is at a corner of the flat side.
Question 9 · AO · medium

The left box shows separate flat pieces. Which figure shows how the pieces look when they are fitted together?

Left box: 3 separate flat pieces: a four-sided piece (about 44% of the total area), a four-sided piece (about 31% of the total area), a four-sided piece (about 25% of the total area).
Show the answer

Answer: C

Count the pieces first: every figure must use each piece exactly once, with nothing added. Then pick one distinctive piece, such as the largest one or one with a curved or sharply pointed edge, and look for it in each figure; pieces may be turned but never flipped over. A figure whose cut lines are in different places has pieces of different sizes and can be crossed out. Here the pieces fit together into a square.

  • A: This figure is a rectangle. The pieces in the left box do not have these shapes, so they cannot fill this outline without gaps or overlaps.
