Question

if all the three angles of a triangle are equal to one other then find the measure of each angle

Answer 1

Let each equal angle be x
then
x+x+x=180 (Angle sum property)
3x=180
x=60
So each angle is 60

Answer 2

Let the angles be X as all angles are equal

using angle sum property of triangle,

<1 + <2 + <3 = 180°

X + X + X = 180°

3X = 180°

X = 180/3 = 60°

Ans. All three angles measure 60°
and it forms an equilateral triangle whose all sides and all angles are equal
