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?

Answer: B
Check one letter at a time. Point P is at the center of the square, and point Q 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 square at a corner, but point P is at the center.
- B (correct): The line joins the center of the square to a corner of the triangle, the same spots as points P and Q in the left box; turning a shape does not move a point on it.
- C: The line ends in the wrong place: it meets the square at the middle of a side, but point P is at the center.
- D: The line ends in the wrong place: it meets the square at the middle of a side, but point P is at the center and it meets the triangle at the middle of a side, but point Q is at a corner.
