Question

If in triangle PQR, PQ = PR then:
a) angle P = angle R b) angle P =angle Q c) angle Q=angle R d) None of these

Answer 1

Given : in triangle PQR, PQ = PR

To Find : Correct option

a) angle P = angle R

b) angle P =angle Q

c) angle Q=angle R

d) None of these

Solution:

in triangle PQR, PQ = PR

In a triangle angles opposite to equal sides are Equal

Angle opposite to PQ  is ∠R

Angle opposite to PR  is  ∠Q

PQ = PR

Hence ∠R = ∠Q

or

∠Q  = ∠R

Hence correct option is c) angle Q=angle R
