In this lesson you will learn about exterior angles by exploring how they are
related to triangles.

Let’s Review
The three angles of a triangle always sum to 180°.
98 + 42 + 40 = 18084 + 69 + 27 = 180111 + 46+ 23 = 180
90 + 68 + 22 = 180

Let’s Review
An exterior angle is formed by extending a side of the polygon.

Core Lesson
The measure of the exterior angle is related to the interior angles of a triangle.
The interior angles of a triangle must sum to 180°.The interior angle next to the extended side and the exterior angle must sum to 180°.68 + 29 + 83 = 180
68 + x = 180

Core Lesson
Find the measures of angle CBD and angle CDB.
Angle CBD = 180 - 106
Angle CBD = 74°74°
Angle CDB = 180 – (76 + 74)
Angle CDB = 30°30°
Angle CBD = 74°Angle CDB = 30°
