Lesson: Adjacent and Vertically Opposite Angles Mathematics • 7th Grade

In this lesson, we will learn 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.

Lesson Plan

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.
