Question

the sum of angles of a triangle is 180 prove this statement

Answer 1

hlo mate.

here is your answer.
________________

we know,
There are three sides and three angles in a triangle.
so, each angle of a triangle measures 60 so, 60 ×3 =180.

hence, it is proved.

Answer 2

According to properties of quadrilaterals,

Sum of the interior angles of any quadrilateral = (n-2)*180 degree

Where, n is the number of sides of the quadrilateral

In a triangle n=3

Therefore,

Sum of interior angles of a triangle = (3-2)*180 degree

                                                          = (1)*180 degree

                                                          = 180 degree

Hence, proved
