Question

Show that sum of all the angles of the triangle is 180 degree
NOT 60 each (not equivalent triangle)

Answer 1

As we know that a triangle has three sides,
_______________________________

n = no. of sides
_______________________

sum of all angles  =  (2n-4)*90

Sum of all angles =[(2*3)-4]*90

Sum of all angles = [6-4]*90


Sum of all angles = 2*90


Sum of all angles of a triangle = 180 


hence, proved


i hope this will help you
