Question

if two angles of a triangle are 60 degree each then so that the triangle is an equilateral triangle​

Answer 1

The Equilateral Triangle has 3 equal sides. The Equilateral Triangle has 3 equal angles. The total sum of the interior angles of a triangle is 180 degrees, therefore, every angle of an equilateral triangle is 60 degrees.

Answer 2

A] We know

1st Angle+2nd Angle+3rd Angle=180°

(Angle Sum Property of Triangle)

Therefore,

60+60+?=180

Take 3rd Angle as X

Therefore

60+60+X=180

120+X=180

X=180-120

X=60°

So All angles are 60°

Therefore it is a EQUILATERAL TRIANGLE.
