there are 60 degrees in one of the angles in an equilateral triangle
The 3 interior angles of any triangle will add up to 180 degrees.
In the equilateral triangle, all the sides are the same length and all the angles are the same size (congruent). Since the sum of the angles of a triangle is always 180 degrees, we can figure out the measure of the angles of an equilateral triangle.Another Answer:-An isosceles triangle has 2 equal base angles plus another angle and the 3 interior angles add up to 180 degrees.
There are 3 angles in a triangle and they add up to 180 degrees
If you add up the degrees of all the angles in a triangle, it adds up to exactly 180 degrees every time.
