The measure of each angle of an equiangular triangle is

A. 45°.

B. 90°.

C. 60°.

D. 120°.

equiangular triangle ⇒ All angles are equal in measurement

180 : 3 = 60°

Answer: Each angle is 60° (C)

C. This is because if it is an equiangular triangle this means that all the angles have the same angle. You know that all the angles in a triangle add up to 180 degrees? You just divided 180 by 3 as there are three angles in a triangle. Which gives you 60 degrees.
