Question

prove that the sum of angles of triangle is 180 degree.​

Answer 1

Answer:

A triangle has 3 sides so,

let the the sides be x,x,x and the ang.sum.prop.of ∆ is 180°

so the equation will be :

x+x+x=180°

3x=180°

x=180/3=60°

so each angle measures 60°.

Checking:-

By adding all the angels we will the get the ang.sum.prop.of.triangle(60+60+60)°=180°

Hope it helps you :)
