Question

the sum of the angle of a triangle is 180 Prove the theorem

Answer 1

Sum of angle of triangle is 180 degree... It's right

Let be given that angle a=50 degree, angle b=70 degree and angle c=?

We now calculate..
Sum of all angles of triangle is 180 degree
A+B+C=180
50+70+c=180
120+c=180
So c=180-120=60.. So angle c is 60 degree

So it's proved
