What is a rotation in geometry?

Back

A rotation is a rigid transformation that turns a shape around a fixed point at a certain angle.

Front

What happens to the coordinates of a point (x,y) when it is reflected over the y-axis?

Back

The x-coordinate changes sign: (-x,y).

Front

What is the definition of a reflection in geometry?

Back

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