Prove that an equilateral triangle must have 60 degrees angles

OK

Step-by-step explanation:

Each of the equal angles of any equilateral triangle is equal to one-third of two right angles (180 divided by 3, which is 60 degrees)’ The compasses thus set at 60 degrees allude to the equilateral triangle and, if the two points were united by a straight line, would form an equilateral triangle.

Step-by-step explanation:

Since all the sides in equilateral triangle are equal ,Angles are also equal

Let it be x

The Angle sum property of triangle is 180

x+x+x=180

3x=180

x= 180/3

=60°
