Congruent Triangle TheoremsUnit 4: Triangles

Page 25: Unit 4. Unit 4: Triangles Definitions Construction of an Equilateral Triangle.

Congruent Triangle TheoremsThe following are eight methods by which to

prove triangles are congruent, without having to find all corresponding parts congruent: SSS, SAS, ASA, AAS, and for right triangles only LL, HA, and HL.

Postulate/Theorems and Similar TrianglesUnit 4: Triangles

Page 36: Unit 4. Unit 4: Triangles Definitions Construction of an Equilateral Triangle.

Three methods may be used to prove triangles similar:

Page 37: Unit 4. Unit 4: Triangles Definitions Construction of an Equilateral Triangle.

Once triangles have been proven similar, scale factors can be used to solve for the missing values.
