What does it mean to rotate a figure?

Back

To rotate a figure means to turn it around a fixed point, called the center of rotation, by a certain angle.

What is reflection in geometry?

Back

Reflection is a transformation that flips a figure over a line, creating a mirror image.

How do you perform a 180° rotation?

Back

To perform a 180° rotation, each point of the figure is turned around the center of rotation to the opposite side.

What is the effect of a 90° clockwise rotation on a point (x, y)?

Back

The effect of a 90° clockwise rotation on a point (x, y) is to transform it to (y, -x).

What happens when you reflect a point over the line y=x?

Back

When you reflect a point (x, y) over the line y=x, it becomes (y, x).
