How do you know if 2 polygons are similar?

Check the angles and corresponding sides: All the angles in a rectangle are congruent to each other and now check that the sides are proportional to each other. 2. Scale factor: If two polygons are similar, then the ratio of the lengths of the two corresponding sides is the scale factor.

Corresponding angles are still congruent
The corresponding side lengths are proportional
