Congruence criteria greg realizes that it is not necessary to check all six pairs of corresponding parts to determine if two triangles are congruent. There is, however, a shorter way to prove that two triangles are congruent! The triangle congruence criteria can be used as shortcuts to show that two triangles are congruent.
In another lesson, we will consider a proof used for right triangles called the hypotenuse leg rule. They are called the sss rule, sas rule, asa rule and aas rule. If two sides in one triangle are congruent to two sides of a second triangle, and also if the included angles are congruent, then the triangles are congruent.
