Question

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

Answer 1

let the angles be x, x and x
we know that sum 3 angles in a triangle is 180
x+x+x=180
3x=180
x=60
60+60+60=180
hence proved

Answer 2

Answer:

or u can prove it another way.

solve, let three angle of triangle =x

x+x+x=180

3x=180

x=180/4

x=60

all angle are 60°

and the sum of three angle become =180 proved
