Lesson Plan: Angle Bisector Theorem and Its Converse Mathematics • First Year of Secondary School
This lesson plan includes the objectives and prerequisites of the lesson teaching students how to use the angle bisector theorem and its converse to find a missing side length in a triangle.
Objectives
Students will be able to
- use the interior and exterior angle bisectors to find missing side lengths in a triangle,
- solve equations that are formed from using the angle bisector theorem,
- use the converse of the angle bisector theorem to solve problems,
- find the lengths of the bisectors of the interior and exterior angles of a triangle.
Prerequisites
Students should already be familiar with
- angle bisectors,
- ratios,
- solving linear and quadratic equations.
