ASA: Angle-Side-Angle Triangle Congruence Postulate
AAS: Angle-Angle-Side Triangle Congruence Theorem
(meaning 2 angles and an outside side of one triangle...)
Objective: (same as Day 3)
GA QCC: #16
Lesson: Triangle Congruence (ASA, AAS)
NAME: ____________________________
1. In the previous day's lesson, you studied the SSS and SAS Triangle Congruence Postulates. In this lesson, there are 2 more postulates/theorems to prove that 2 triangles are congruent (to each other):
ASA: Angle-Side-Angle Triangle Congruence Postulate
AAS: Angle-Angle-Side Triangle Congruence Theorem
(meaning 2 angles and an outside side of one triangle...)
2. In the above figure, are the 2 triangles congruent? ____________
Why? _____________________________________________________
3. In the next figure (above), are the triangles congruent? ____________
Why?_______________________________________________________
4. Click HERE (Figure 3) to answer the following questions. To prove the triangles are congruent, state which postulate/theorem you would use (ASA or AAS), both, or neither.
