Question

How to prove that each angle of an equilatrel triangle is equal to 60 degree??

Answer 1

Let one angle be 'x'
Since, all angles of an equilateral triangle are Equal,hence each of its angle=x
Now,
x+x+x=180° {angle sum property of a triangle}
3x =180°
x =180°÷3
x =60°

Hence proved that all angles of an equilateral triangle are 60°
