Front

What best describes a translation in the coordinate plane?

Back

Sliding a figure without turning or flipping it.

Front

What is a composition of transformations?

Back

Front

What is a dilation in geometry?

Back

Enlarging or reducing a figure proportionally.

Front

What is the difference between a translation and a reflection?

Back

A translation slides a figure, while a reflection flips it over a line.
