Q1 of 69 Page 9

If all the three angles of a triangle are equal, then each one of them is equal to

Let,

A, B and C be the angles of


A = B = C (Given)


We know that,


∠A + ∠B + ∠C = 180o


∠A + ∠A + ∠A = 180o


3∠A = 180o


∠A = 60o


Therefore,


∠A = ∠B = ∠C = 60o


Thus, each angle is equal to 60o.
