Congruence Definition Two triangles are congruent if their corresponding sides are equal in length and their corresponding interior angles are equal in measure. We use the symbol ≅ ≅ to show congruence. Corresponding sides and angles mean that the side on one triangle and the side on the other triangle, in the same position, match.
Chapter 4 26 Glencoe Geometry Study Guide and Intervention (continued) Proving Triangles Congruent—SSS, SAS SAS Postulate Another way to show that two triangles are congruent is to use the Side-Angle-Side (SAS) Postulate.

To prove that OP ≅ OQ is enough to prove that OPM ≅ OQM. 1) ∠QOM ≅ ∠POM (OL is a bisector), 2) ∠OQM ≅ ∠OPM = 90° 3) OM is a shared side. Therefore, the both triangles OPM and OQM are congruent by Angle-Angle-Side. Problem 4 Prove that if CP is an altitude and a bisector then the triangle ABC is isosceles.

You have learned four ways to prove that triangles are congruent. • Side-Side-Side (SSS) Congruence Postulate (p. 212) • Side-Angle-Side (SAS) Congruence Postulate (p. 213) • Angle-Side-Angle (ASA) Congruence Postulate (p. 220) • Angle-Angle-Side (AAS) Congruence Theorem (p. 220)
Which theorem would you use to prove the two triangles congruent if Z is the midpoint of segment YP and segment XQ? SSS Congruence Which theorem would you use to prove the two triangles congruent?
AAS Congruence A variation on ASA is AAS, which is Angle-Angle-Side. Recall that for ASA you need two angles and the side between them. But, if you know two pairs of angles are congruent, then the third pair will also be congruent by the Angle Theorem. Therefore, you can prove a triangle is congruent whenever you have any two angles and a side.
