Warm-Up Exercises Bell Work Tell whether the pair of triangles is congruent or not and why. Warm-Up Exercises Notes Angle-Side-Angle (ASA) Congruence Postulate If two angles and the included side of one triangle are congruent to two angles and the included side of a second triangle, than the two triangles are congruent. Warm-Up Exercises Notes Angle-Angle-Side (AAS) Congruence Theorem If two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of a second triangle, then the two triangles are congruent. Warm-Up1Exercises EXAMPLE Identify congruent triangles Can the triangles be proven congruent with the information given in the diagram? If so, state the postulate or theorem you would use.
