Question

prove that all angles of a equilateral triangle are of 60 degree

Answer 1

Hello Dear!!!

Here's your answer..

We know that..

measure of three angles in a triangle is same

and sum of all angles in a triangle is 180

let,

the angles in a equilateral triangle be 'x'

x+x+x = 180

3x= 180

x = 180/3

x = 60

The angles of equilateral triangle are 60,60,60

Answer 2

The all angles are equal in a equilateral triangle because all three sides are equal.
And we know that the sum of all angles of a triangle is always 180° .
So ,
x+x+x = 180°
3x=180°
x= 180° /3
x= 60° .
Hence it is proved that all the angles are of 60° in an equilateral triangle .
