Question

sgow that the angles of an equilateral triangle are 60 degree each

​

Answer 1

All angles of a equilateral triangle are equal so let one angle be x ,z,y

x=z=y

x+z+y= 180 Angle sum Property

3x=180

x=60

x=y=z=60 degree

Answer 2

Answer:

All sides and angles of a eqilateral triangle are equal.

i.e angle 1=angle 2= angle 3.

(assume all angles to be x as they are equal)

x+x+ x= 180°

( sum of all angles of a triangle = 180° )

i.e. 3x= 180°

x= 180° ÷3

x= 60°

therefore each angle of a equilateral triangle is of 60°.
