Two congruent figures have exactly the same shape and size. If two triangles are congruent, then their corresponding parts are equal. We will study the five congruence criterion such as SAS, ASA AAS, SSS, and RHS. If two sides and included angle of one triangle are equal to two sides and the included angle of the other triangle, then the two triangles are congruent. [SAS congruence rule] If two angles and the included side of one triangle are equal to two angles and included a side of the other triangle, then the two triangles are congruent. [ASA congruence rule] If two angles and one side of a triangle are equal to two angles and the corresponding side of the other triangles, then the two triangles are congruent. [AAS congruence rule] If three sides of one triangle are equal to three sides of another triangle, then the two triangles are congruent. [SSS congruence rule] If in two right triangles, hypotenuse and one side of a triangle are equal to the hypotenuse and one side of the other triangle, then the two triangles are congruent.
