The internal angles of a triangle add up to 180 degrees so in an equilateral triangel each internal angle must be 60 degrees, as 3 x 60 = 180.
Each of the 3 angles in an equilateral triangle are 60 degrees.
60 degrees
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.
