equiangular triangle
The sum of the internal angles in a triangle is equal to 180 degrees. An equiangular triangle, otherwise known as an equilateral triangle, has three angles of the same length, and three angles of the same size. The size of each angle is 180 / 3 = 60 degrees.
Yes because the only way a triangle can be equiangular is if every angle is 60 degrees
