What is an exterior angle of a triangle?

Back

An exterior angle of a triangle is formed by one side of the triangle and the extension of an adjacent side. It is equal to the sum of the two remote interior angles.

If one interior angle of a triangle measures 40 degrees and another measures 60 degrees, what is the measure of the exterior angle adjacent to the 40-degree angle?

Back

The exterior angle is 60 degrees + 40 degrees = 100 degrees.

What is the sum of the measures of the exterior angles of a triangle?

Back

The sum of the measures of the exterior angles of a triangle is always 360 degrees.

Front

What is the measure of angle b if angle a is 36 degrees and angle c is 108 degrees?

Back

Angle b is 36 degrees, as it is the exterior angle formed by extending the side opposite angle a.
