Question

prove that all the angles of an equilateral triangle measures 60°​

Answer 1

Answer:

Step-by-step explanation:

sum of measure of all angle of triangle is 180

take any three angles

m<a +m<b+ m<c =180°

take all angles as x

x+x+x = 180

3x =180°

x=60

so, all the angles of triangle are 60°

Answer 2

To Prove:- All angle of an equilateral triangle is 60°.

Proof:- We know that in an equilateral triangle all sides are equal.

So let us take any one side as x.

Such that,

x+x+x=180° {Angle sum property of a triangle}

3x=180°

x=180°/3

x=60°

Hence, proved.

Hope this helps you.
