What does it mean for two figures to be similar?

Back

Two figures are similar if they have the same shape but not necessarily the same size, meaning their corresponding angles are equal and their corresponding sides are in proportion.

Front

If the scale factor of two similar triangles is 2:3, what does this imply about their areas?

Back

The area of the larger triangle is (3/2)² = 9/4 times the area of the smaller triangle.

Front

How do you find the scale factor between two similar polygons?

Back

To find the scale factor, divide the length of a side of one polygon by the length of the corresponding side of the other polygon.
