Lesson Plan: Adjacent and Vertically Opposite Angles Mathematics
This lesson plan includes the objectives and prerequisites of the lesson teaching students how to identify adjacent and vertically opposite angles and use the properties of angle bisectors, vertically opposite angles, and angles around a point to solve related problems.
Objectives
Students will be able to
- identify that angles are adjacent if they share a common side and a common vertex,
- find the measure of an angle made of two or more adjacent angles,
- understand that an angle bisector is a ray that divides an angle into two halves,
- identify vertically opposite angles,
- find the measure of vertically opposite angles,
- use the properties of vertically opposite angles and accumulative angles at a point to solve problems.
Prerequisites
Students should already be familiar with
- geometrical concepts such as angles and their measures, rays, and straight lines,
- types of angles,
- the sum of angles in a triangle,
- solving linear equations,
- complementary and supplementary angles.
