Question

Prove that measure of each angle of an equilateral triangle is 60^0 .

Answer 1

a measure of an equilateral triangle is 180 and had 3 sides, so, we will divide180 by 3 hence answer is 60 and proved each angle is 60

Answer 2

Q. Prove that measure of each angle of antibiotics equilateral triangle is 60°.

Let ΔABC be an equilateral triangle.

AB = BC = CA

As Angles opposite to equal sides of a triangle are equally.

AB = BC & BC = CA

C = A and A = B

A = B = C

∠A + ∠B + ∠C = 180°

∠A + ∠A +∠A = 180°

3 A = 180°

∠A = 180/3

∠A = 60°

∠A = ∠B = ∠C = 60°

Hence proved !
