The Exterior Angles of a Triangle

Objective: Students will solve problems that involve an exterior angle of a triangle.


Note: An exterior angle of a triangle is equivalent to the sum of its two non-adjacent interior angles.


Example #1: Find x. sum of its two non-adjacent interior angles.

x

120

40


Example #2: Find x. sum of its two non-adjacent interior angles.

5x

2(4x – 30)

x + 20


Example #3: Find x, then find the measure of the interior angles at A and B.

4x + 10

3x – 20

A

5(x – 14)

B

mA= 3(25) – 20 = 55

mB= 5(25 – 14) = 55
