Question

Prove that each angle of an equilateral triangle is 60 degree

Answer 1

Hello friend

Here is your answer

In equilatetal triangle all 3 sides are equal and as per isosceles theorem it has 2 sides equal and hence all three angles name as x so by angle sum property

a+b+c=180

a=b=c=x

x+x+x=180

3x=180

x=60

And as x=a=b=c

all angles of a equilateral triangle are

equal...

sum of interior angles of triangle is 180 degree..

let each angle of equilateral triangle be x

so x+x+x=180

3x=180

x=60
