What is a rotation?

Back

A rotation is a transformation that turns a figure around a fixed point called the center of rotation.

What is a reflection?

Back

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

What does it mean to reflect a figure?

Back

To reflect a figure means to flip it over a line, resulting in a mirror image.

How does a translation affect the coordinates of a point?

Back

In a translation, each point of the figure moves the same distance in the same direction, changing its coordinates accordingly.
