Similar Polygons

Two polygons are similar if they have same shape, but not the same size.

Similar polygons are polygons, if their corresponding angles are congruent, and the measure of their corresponding sides are proportional.

The ratio of length of their corresponding sides are all in a constant ratio, and their corresponding angles are equal.

In below triangles ABC and PQR corresponding angles are equal so,
                            ∠A = ∠P
                            ∠B = ∠Q
                            ∠C = ∠R

The ratio of length of their corresponding sides are equal so,

                 AB/PQ = AC/PR = BC/ QR
