Question

if ABC is equilateral triangle then prove that all angles are 60 degree

Answer 1

All sides are equal so all the angles are equal ...take each angle as x
now sum of all angles will be 180°
×+×+×=180°
3×=180°
×=60°

Answer 2

Hello friends!!
.
I would love to help you out!

A triangle has 3 sides, and the ang sum property of a triangle is 180 degree.. So angle a plus angle b plus angle c equal to 180 degree.. In an equilateral triangle the measure of each angle is same, keeping the angle sum property in mind, if we calculate then, each side has to be 180 degree.. We can prove this by dividing 180 degree by 3.
X+x+x=180°
3x=180°
X= 180°÷3
X=60°
thank you, hope it helps
