Question

If all three angle of a triangle are equl, then each one of them is equl to

Answer 1

If all the three angles of triangle are equal then the triangle is called as Equilateral Triangle.

Properties of an equilateral triangle are -

+ All sides are equal i.e., A = B = C
+ All angles are equal i.e., /A = /B = /C = 60°

Hence, each angle must be of 60°.

Answer 2

let us take sides a,b,and c.
given:
a=b=c
solution:
a+b+c=180° (by asp)
let us take
a=b=c=y
so,a+b+c=180°
y+y+y=180°
3y=180°
y=180÷3=60°
