Topic: Angle Side Angle

Learning Objective: students will be able to determine the congruence between triangles when given two angles and it’s included side for various triangles

Students will be able to state the Angle Side Angle postulate.
Common Core Standard: CCSS.Math.Content.HSG.CO.B.7
Use the definition of congruence in terms of rigid motions to show that two triangles are congruent if and only if corresponding pairs of sides and corresponding pairs of angles are congruent.
Explain how the criteria for triangle congruence (ASA, SAS, and SSS) follow from the definition of congruence in terms of rigid motions.


Key Vocabulary: Angle-Side-Angle postulate


Prior Knowledge: SAS postulate, SSS postulate, Corresponding Side, Corresponding Angle, Congruence.
