Question

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

Answer 1

Answer:

angle a + angle b + angle c =180

suppose that,

angle a = 60°

angle b=40°

angle c=?

so, how we find angle c

according to the formula

angle a + angle B + angle c = 180°

60°+40°+ angle c =180°

100°+angle c =180°

angle c = 180°-100°

angle c = 80°
