This is the currently selected item. In the diagrams below, if ac = qp, angle a = angle q, and angle b = angle r, then triangle abc is congruent to triangle qrp. Congruent triangles are triangles having corresponding sides and angles to be equal.

Comparing one triangle with another for congruence, they use three postulates. Triangle congruence criteria • use the definition of congruence in terms of rigid motions to show that two triangles are congruent if and only if corresponding pairs of sides and corresponding pairs of angles are congruent (cpctc). Calculating angle measures to verify congruence.

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. This criterion for triangle congruence is one of our axioms. More formally, two sets of points are called congruent if, and only if, one can be transformed into the other by an isometry, i.e., a combination of rigid motions, namely a translation, a rotation, and a reflection.

Use triangle congruence criteria, rigid motions, and other properties of lines and angles to prove congruence between different triangles. In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other. Explain how the criteria for triangle congruence (asa, sas, and sss) follow from the definition of congruence in terms of rigid motions.
