Question

show that the angle of an equelateral triangle are 60° each

Answer 1

In equilateral triangle,
all amgles are equal

let the angles be x.

we know,sum of angles of a triangle=180

x+x+x=180
3x=180
x=60

done.

Answer 2

We know that sum of angles of all equilateral triangles are 60degree each x+x+x=180
3x=180
x=180/3
x=60
