2. SSS Postulate If the sides of one triangle are congruent to the sides of a 2 nd triangle, then the triangles are congruent If the sides of one triangle are congruent to the sides of a 2 nd triangle, then the triangles are congruent

3. SAS Postulate If 2 sides & the included angle of one triangle are congruent to 2 sides & the included angle of another triangle, then the triangles are congruent. If 2 sides & the included angle of one triangle are congruent to 2 sides & the included angle of another triangle, then the triangles are congruent. 30

4. ASA Postulate If 2 angles & the included side of one triangle are congruent to 2 angles & the included side of another triangle, the triangles are congruent. If 2 angles & the included side of one triangle are congruent to 2 angles & the included side of another triangle, the triangles are congruent. 30 95 30 95

5. AAS Theorem If 2 angles & a nonincluded side of one triangle are congruent to the corresponding 2 angles & side of a 2 nd triangle, the 2 triangles are congruent. If 2 angles & a nonincluded side of one triangle are congruent to the corresponding 2 angles & side of a 2 nd triangle, the 2 triangles are congruent. 30 95 30 95
