Question

prove that sum of interior. angle of triangle = 180 pe​

Answer 1

Answer:

sum of all sides of a triangle is 180°

the angles may be 30°-60°-90° ( by 30°-60°-90° theorem)

the angles may be 45°-45°-90° (by 45°-45°-90° theorem)

Answer 2

Answer:

Step-by-step explanation:

angle a + angle b + angle c = 180

let the angle be x

x + x + x = 180

3x=180

x =180/3

x=60
