Question

Prove that the sum of the angles of a triangle is 180°

Answer 1

by formula  -  (2n-4) * 90             [n is denoted to the number of side]
     
as we know that triangle has three sides

then

proof  :-  [(2n -4) *90]  

= [(2*3) - 4] *90

= (6-2) * 90

= 2*90

= 180

hence proved that the sum of angles of triangle is 180
