Q:
# How Many Degrees Does an Equilateral Triangle Have?

**The sum of the interior angles of an equilateral triangle equals 180 degrees.** This stems from the fact that the combined interior angles of any given triangle always add up to this same amount, according to the Monterey Institute for Technology and Education.

This knowledge is often used to determine the measure of a triangle’s unknown interior angle by combining the measures of the other two known angles and subtracting the resulting sum from 180. The general formula for finding the sum of the interior angles of any polygon is 180 multiplied by n – 2, where n is the number of sides used to form the polygon.
