What is Triangle Similarity?

Back

Triangle similarity refers to the property of two triangles having the same shape but possibly different sizes. This means their corresponding angles are equal and their corresponding sides are in proportion.

What does AA Similarity stand for?

Back

AA Similarity stands for Angle-Angle Similarity. It states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.
