Unit 4 Congruence in Triangles
In this unit, we will learn about the different types of triangles and the ways to determine triangle congruence. We'll classify the different types of triangles, based on side lengths and angle measurements. Next, we'll discuss congruence . Congruent figures have the same shape and size.
