Similarity and Congruence Geometry

If two triangles are similar, what can you say about the ratio of their corresponding sides?

• The ratio of their corresponding sides is different for each pair of triangles.

• The ratio of their corresponding sides is constant.

• The ratio of their corresponding sides is random.
