How do you find the measure of a missing interior angle in a triangle?

Back

The sum of the interior angles in a triangle is always 180 degrees. Subtract the known angles from 180 to find the missing angle.

What is the measure of the missing interior angle if the other two angles are 60 degrees and 40 degrees?

Back

The missing angle is 80 degrees (180 - 60 - 40 = 80).

Front

What is the value of x if Angle 1 is 31 degrees and it is a Vertical Angle to Angle x?

Back

x = 31 degrees because Vertical Angles are equal.
