Front

What is a translation in geometry?

Back

A translation is a transformation that moves every point of a shape the same distance in the same direction.

Front

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

Back

The new coordinates will be (y, -x).

Front

What is the result of a 90° counterclockwise rotation of point (x, y)?

Back

The new coordinates will be (-y, x).

Front

What is a dilation in geometry?

Back

A dilation is a transformation that changes the size of a shape but not its shape.

Front

What does it mean for two shapes to be similar?

Back

Two shapes are similar if they have the same shape but not necessarily the same size.
