Define translation in geometry.

Back

Translation is a transformation that slides a shape from one position to another without turning or flipping it.

What is rotation in geometry?

Back

Rotation is a transformation that turns a shape around a fixed point called the center of rotation.

Explain reflection in geometry.

Back

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

What is dilation in geometry?

Back

Dilation is a transformation that changes the size of a shape but keeps its proportions the same.

How do you identify a rotation transformation?

Back

A rotation transformation can be identified by the angle of rotation and the direction (clockwise or counterclockwise).
