Since the equilateral triangle has 60 degree angles, we can solve for the three angles as shown. Construct an equilateral triangle along the top side as follows: The two sides opposite the 80 degree angles are equal. The third angle is 180 – 20 – 80 = 80 degrees, so this is an isosceles triangle. First, we solve for the third angle in the large triangle. We will solve the problem in several steps.
