Angles of a Triangle

Unit 3: Parallel Lines
Lesson 3 of 5

Objective: SWBAT prove that the sum of the measures of the angles of a triangle is 180 degrees, and SWBAT solve problems involving the interior and exterior angles of triangles.

Big Idea: Students learn about the different types of triangles, the relationships between the interior and exterior angles of a triangle, and apply their knowledge to numerical problems and constructions.
