Congruent Triangles Opening routine Congruent Triangles Opening routine Unit I: Congruence, Proof and Constructions Lesson 6 Congruent Triangles Objective: Explain using similarity transformations the meaning of similarity for triangles as the equality of all corresponding pairs of angles and the proportionality of all corresponding pairs of sides. Essential Question: How does the SSS Triangle Congruence Postulate tell you about triangles? Lesson 6 Congruent Triangles Vocabulary Congruent: Two figures are congruent when coinciding at all points when superimposed. Side-Side-Side (SSS) Postulate: If three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent. Side-Angle-Side (SAS) Postulate: If 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. Lesson 6 Congruent Triangles Vocabulary Included Angle: Given two sides of a triangle, the angle they form is called included angle. Included Side: Given two angles of a triangle, the side which endpoints are the vertices of the two angles is called included side. Angle-Side-Angle (ASA) Postulate: If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.
