Definitions and Basic Facts (09:35)
Proving Triangles Congruent (09:40)
PROPERTIES OF TRIANGLES
In this unit you will begin with a review of triangles and their properties. You will look at classifying triangles by both angles and sides. You will examine the Angle Sum Theorem and other theorems that apply to triangles. In the final part of this unit, you will explore congruency between triangles by examining their corresponding angles and sides and learn a very useful definition of congruent triangles (CPCTC).
