CPCTC is an acronym for ‘Corresponding Parts of Congruent Triangles are Congruent’. In this article learn about different congruence methods along with solved examples and interesting practice questions. Conditions of Congruence in Triangles Two triangles are said to be congruent if both the triangles have similar size and Congruent triangles are triangles that have the same size and shape, with corresponding sides and angles equal in measure, representing identical configurations when overlapped or superimposed. Let’s explore its types, conditions, and proofs. Since two angles of ABC are congruent to two angles of PQR, the third pair of angles must also be congruent, so ∠C≅∠R, and ABC≅ PQR by ASA. If the hypotenuse and one leg of a right triangle are equal to the hypotenuse and one leg of another right triangle, then the two right triangles are congruent.
