What is Triangle Similarity?

Back

Triangle similarity refers to the property of two triangles having the same shape but not necessarily the same size. 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.

What does SSS Similarity stand for?

Back

SSS Similarity stands for Side-Side-Side Similarity. It states that if the three sides of one triangle are in proportion to the three sides of another triangle, then the triangles are similar.
