What is the Triangle Sum Theorem?

Back

The Triangle Sum Theorem states that the sum of the interior angles of a triangle is always 180 degrees.

What is the measure of an angle if the other two angles in a triangle are 25 degrees and 155 degrees?

Back

25 degrees

Front

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

Back

Subtract the sum of the known angles from 180 degrees.

What is the formula to calculate the third angle in a triangle?

Back

Third angle = 180 degrees - (first angle + second angle)
