Prove Triangles Congruent by SSS Prove Triangles Congruent by SSS • Side-Side-Side (SSS) Congruence Postulate: Prove Triangles Congruent by SSS • Side-Side-Side (SSS) Congruence Postulate: – If three sides of one triangle are congruent to three sides of a second triangle, then the two triangles are congruent. Prove Triangles Congruent by SSS • Side-Side-Side (SSS) Congruence Postulate: – If three sides of one triangle are congruent to three sides of a second triangle, then the two triangles are congruent. – In other words: Prove Triangles Congruent by SSS • Side-Side-Side (SSS) Congruence Postulate: – If three sides of one triangle are congruent to three sides of a second triangle, then the two triangles are congruent. – In other words: • If all the sides are the same, the triangles are the same. Prove Triangles Congruent by SSS • Side-Side-Side (SSS) Congruence Postulate: – If three sides of one triangle are congruent to three sides of a second triangle, then the two triangles are congruent. – In other words: • If all the sides are the same, the triangles are the same.
