What are similar figures?

Back

Similar figures are shapes that have the same shape but may differ in size. Their corresponding angles are congruent, and their corresponding sides are in proportion.

If two triangles are similar, how can you find the length of a side in one triangle if you know the corresponding side in the other triangle?

Back

You can set up a proportion using the lengths of the corresponding sides and solve for the unknown length.
