Similar Triangles
In geometry, triangles that have identical angles but different lengths of side. They are, therefore, identical shapes but different sizes. If each angle in a triangle corresponds to an identical angle in another triangle, then the two triangles are similar.
For example, triangles ABC and DEF are similar:
Similarity can apply to any two-dimensional (2D) shapes if their corresponding angles are the same.
