Let’s try mental rotation.
Look at two shapes. Is the second one turned, or is it a mirror image?
First, an example.
These are the same shape. The right figure has been turned a quarter turn. Follow the blocks from one end: the same bends stay connected.
Try three questions. We’ll explain each answer.

Could you turn one figure to match the other?
1 of 3
Choose an answer. We’ll explain it before you move on.
Same, rotated. The right figure is the left figure turned a quarter turn. Its six blocks and the order of its bends stay the same.
Same shape, or a mirror image?
2 of 3
Choose an answer. We’ll explain it before you move on.
Mirror image. The right figure reverses the shape. Turning it can line up one part, but cannot make all six blocks match at once.
Take your time. Could these two figures match?

Same, rotated. The right figure has made a half turn. Its position changes, but the blocks and their connections do not.
Take your time.

A look at your answers
Start at one end and follow the bends. Turning keeps the blocks joined the same way; a mirror image reverses the shape.
Question 1
Same, rotated. The right figure is the left figure turned a quarter turn. Its six blocks and the order of its bends stay the same.
Question 2
Mirror image. The right figure reverses the shape. Turning it can line up one part, but cannot make all six blocks match at once.
Question 3
Same, rotated. The right figure has made a half turn. Its position changes, but the blocks and their connections do not.
