Question

15.Show that the angles of an equilateral triangle xe 60° each.
​

Answer 1

Step-by-step explanation:

Let take a triangle abc,

let take angle a = x

because abc is an equilateral triangle all the angles are equal .

Hence,

a = b = c = x

and by using the angle sum property of the triangle we get :-

a + b + c = 180

so keeping the value of a, b and c,

we get

x+x+x = 180

3x = 180

x = 180/3

x = 60 degree

and x = a = b = c

hence,

a = 60 degree

b = 60 degree

c = 60 degree
