Definition: Similar Triangles

Back

Triangles that have the same shape but may differ in size; corresponding angles are equal and corresponding sides are in proportion.

Front

Proportionality in Similar Triangles

Back

In similar triangles, the ratios of the lengths of corresponding sides are equal.

Front

Angle-Angle (AA) Similarity Postulate

Back

If two angles of one triangle are equal to two angles of another triangle, the triangles are similar.

Front

Side-Side-Side (SSS) Similarity Theorem

Back

If the corresponding sides of two triangles are in proportion, then the triangles are similar.

Front

Side-Angle-Side (SAS) Similarity Theorem

Back

If one angle of a triangle is equal to one angle of another triangle and the sides including these angles are in proportion, then the triangles are similar.
