Proving Triangles Similar

Front

What does SAS~ stand for in triangle similarity?

Back

SAS~ stands for Side-Angle-Side similarity, which states that if two sides of one triangle are proportional to two sides of another triangle and the included angles are equal, then the triangles are similar.

What is the AA~ similarity criterion?

Back

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

How can you determine if two triangles are similar using the SSS~ criterion?

Back

SSS~ stands for Side-Side-Side similarity, which states that if the lengths of the corresponding sides of two triangles are proportional, then the triangles are similar.

What is a similarity statement in geometry?

Back

A similarity statement is a statement that indicates that two geometric figures are similar, often written in the form of ΔABC ~ ΔDEF, meaning triangle ABC is similar to triangle DEF.

What does it mean if two triangles are not similar?

Back

If two triangles are not similar, it means they do not have the same shape, which can be due to differences in angle measures or side lengths.
