Corresponding Sides of Similar Figures

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 the lengths of their corresponding sides are proportional.

What does it mean for two sides to be corresponding sides?

Back

Corresponding sides are the sides of similar figures that are in the same relative position. For example, in two similar triangles, the side opposite the same angle in each triangle is a pair of corresponding sides.

What is the scale factor in similar figures?

Back

The scale factor is the ratio of the lengths of two corresponding sides of similar figures. It indicates how much one figure has been enlarged or reduced compared to the other.

How do you determine which sides correspond in similar triangles?

Back

To determine which sides correspond in similar triangles, match the angles of the triangles. The sides opposite equal angles are corresponding sides.
