Question

Geometry A: Lesson 9. Congruent Triangles Unit Test.

has ANYONE at connections done this who would be willing to give me answers? I'm behind!

Answer 1

There are three types of congruence
1) SSS Congruence - It's usually a postulate. If two triangles have 3 congruent sides, then they are congruent.
2) SAS Congruence - It's usually a postulate. If two triangles have 2 congruent sides congruent and the INCLUDED angle congruent, then the 2 triangles are congruent.
3) ASA and AAS Congruence - ASA is a postulate. AAS is a theorem. ASA - If two triangles have 2 congruent angles and one included side congruent, then the 2 triangles are congruent. AAS - If two triangles have 2 congruent angles and one nonincluded side congruent, then the 2 triangles are congruent.
