**An equilateral triangle has all three interior angles 60°.**

⇒ Draw a straight line, PQ that will be one leg of the angle.

⇒ With a compass on P, Set the width half of PQ

⇒ Draw an arc above P and crossing PQ

⇒ Where the arc crosses PQ, make an arc across the first.

⇒ Draw a straight line toward the x.

AD=AE(radii of same arc) - 1ST

AD=DE(arc of same radius) - 2ND

from 1 and 2

AD=AE=DE

in triangle as all the 3 sides are equal..therefore it is an equilateral triangle...

A=E=D=x

by angle sum property of triangle,

A+E+D=180

3x=180

x=180/3

x=60

therefore A=E=D=60
