Question

in triangle pqr angle p equal to 60 degree and angle q equal to 40 degree what side of this triangle is the smallest . Give reasons for your answer.​

Answer 1

Anwer is pq

Using angle sum property of triangle

∠P+∠Q+∠R=180

∘

⇒60

∘

+50

∘

+∠R=180

∘

⇒∠R=180

∘

−110

∘

=70

∘

So ∠R is the largest angle and side opposite to largest angle is the longest side.

∴PQ is the longest side.
