Front

What is the definition of dilation in geometry?

Back

A transformation that produces a figure similar to the original by enlarging or reducing it based on a scale factor.

Front

What is a scale factor in dilation?

Back

The ratio of the length of a side of the image to the length of the corresponding side of the original figure.

Front

What does it mean for two figures to be similar?

Back

They have the same shape but may differ in size.

Front

What is the effect of a scale factor greater than 1 in dilation?

Back

The figure is enlarged.

Front

What is the effect of a scale factor less than 1 in dilation?

Back

The figure is reduced.
