Question

you can prove that two circles are similar to each other because the ratio of radius to radius taken anywhere within two circles is uniform. what is the process of growing or shrinking a circle from one to the other called? (1 point)

○ dilation

○ rotation

○ reflection

○ translation

Explanation:

Rotation, reflection, and translation are rigid transformations that preserve the size of a shape. Only dilation changes the size of a figure by scaling it up or down while maintaining its shape, which matches the description of growing or shrinking a circle to create a similar one.

Answer:

dilation
