Question

figures that have the same shape but different sizes, with proportional corresponding sides and equal corresponding angles, are called __________ figures.
a dilation with a scale factor greater than one is called an __________.
a dilation with a scale factor between zero and one is called a __________.

Explanation:

First Question:

By the definition of similar figures, figures with the same shape (equal corresponding angles) and proportional corresponding sides (different sizes) are called similar figures.

A dilation with a scale factor \( k>1 \) enlarges the original figure, so it's called an enlargement.

A dilation with a scale factor \( 0 < k < 1 \) reduces the size of the original figure, so it's called a reduction.

Answer:

similar
