Lesson: Angle Relationships Mathematics

In this lesson, we will learn how to identify different types of angles and use relationships between their measures to solve problems.

Lesson Plan

Students will be able to

identify adjacent angles and the measure of an angle made of two or more adjacent angles,
identify a pair of complementary or supplementary angles and find the measure of an angle given its complementary or supplementary angle,
identify vertically opposite angles and find the measure of an angle given that of its vertically opposite one,
use the properties of angles on a straight line and angles around a point to solve problems that include all angle relationships,
understand that an angle bisector is a ray that divides an angle into two halves,
solve word problems using properties of angles.

Q1:

Are and adjacent angles?

Q2:

Find the sum of the two adjacent angles from the given angles in the diagram.

Q3:

Classify the following pair of angles as complementary, supplementary, vertical, or neither.
