Similar Figures Review

Front

What are similar figures?

Back

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

Front

What is the definition of corresponding sides?

Back

Corresponding sides are the sides of similar figures that are in the same relative position. For example, in similar triangles, the side lengths are proportional.

What does it mean if two figures are congruent?

Back

Congruent figures are identical in shape and size, meaning all corresponding sides and angles are equal.

What is the difference between similar and congruent figures?

Back

Similar figures have the same shape but different sizes, while congruent figures have the same shape and size.
