What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning all corresponding sides and angles are equal.

What is the difference between SAS and ASA?

Back

SAS requires two sides and the included angle to be equal, while ASA requires two angles and the included side to be equal.

Front

What is the purpose of triangle congruence theorems?

Back

Triangle congruence theorems are used to prove that two triangles are congruent, which means they have the same size and shape.
