Question

PQRS is a quadrilateral with PQ| |SR. if S=R=60°,find P and Q​

Answer 1

Answer:

By angle sum property of a quadrilateral,

∠P+∠Q+∠R+∠S=360

∘

⇒50

∘

+50

∘

+60

∘

+∠S=360

∘

⇒∠S = 200

∘

Here, we can see that ∠S is greater than 180

∘

which implies that the quadrilateral PQRS is concave.
