Question

prove that all angle of and equilateral triangle equal​

Answer 1

let Triangle abc be an equilateral triangle
Since triangle abc is an equilateral triangle,
Hence,angle a=angle b=angle c= x
So, angle a+angle b+angle C=180°
x+x+x=180°
3x=180
x=180/3
x=60°
This says that all angle are in equal amount.......
that is angle a=angle b=angle c=60°
