By the Alternate Interior Angles Theorem. To make this website work, we log user data and share it with processors. This can be expressed as the following postulate. The following postulate uses the idea of an included side. Prove triangles congruent by using the definition of congruence. Two polygons are congruent polygons if and only if their corresponding sides are congruent. The property of triangle rigidity gives you a shortcut for proving two triangles congruent.

Name the angle formed by AB and AC. Two polygons are congruent polygons if and only if their corresponding sides are congruent. Verifying Triangle Congruence Show that the triangles are congruent for the given value of the variable. The following postulate uses the idea of an included side. The property of triangle rigidity gives you a shortcut for proving two triangles congruent. Corresponding angles and corresponding sides are in the same position in polygons with an equal number of sides.
