How can I make a skateboard ramp that is 160 degrees with the ground?
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°
