Congruent Figures

Naming figures must be done correctly, so that you can write accurate congruence statements.

If you are trying to determine if two triangles are congruent, you will compare the angles and the sides. If all pairs of anglesare congruent and all pairs of sides are congruent, then the triangles are congruent to each other.

Postulate shortcuts to Proving Congruence of Triangles

SSSif the three sides of one triangle are congruent to the three sides of another triangle, the triangles are congruent.

SASif two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent

Postulate shortcuts to Proving Congruence of Triangles

ASAif two angles and the included side of one triangle are congruent to two angles and the included side of another triangle the triangles are congruent.

AASif two angles and a non-included side of one triangle are congruent to two angles and a non-included side of another triangle, then the triangles are congruent.
