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 that 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 SAS Similarity stand for?

Back

SAS Similarity stands for Side-Angle-Side Similarity. It states that if two sides of one triangle are in proportion to two sides of another triangle and the included angles are equal, then the triangles are similar.

Can two triangles be similar if they have one angle equal?

Back

No, two triangles cannot be similar with only one angle equal. At least two angles must be equal for the triangles to be similar (AA Similarity).
