Definition: polygons are similar if their corresponding (matching) angles are congruent (equal in measure) and the ratio of their corresponding sides are in proportion.
These triangles are similar because all of the angles are equal and the sides are proportional:
The scale factor is 2.
Each side of the smaller triangle is multiplied by 2 to create the larger triangle.
