Geometry Unit 5 Triangles Review

Which is the best definition of similarity?

• If two figures have congruent corresponding angles, they are similar.

• If two figures have proportional side lengths, they are similar.

• If there's a sequence of rigid transformations that take one figure to another, they are similar.

• If there's a sequence of rigid transformations and dilations that take one figure to another, they are similar.
