Question

PQRS is a quadrilateral such that angle p = angle Q ,angle R = angle S . if angle p = 2 angle R find the angles of the quadrilateral ​

Answer 1

∠P = 120 ° , ∠Q = 120 ° , ∠R = 60 ° and ∠S = 60 °

Step-by-step explanation:

Given ,

∠P = ∠Q, ∠R = ∠S and ∠P = 2∠R

To find, the measure of each angle = ?

By angle sum property of quadrilateral ,

∠P + ∠Q + ∠R + ∠S = 360 °

⇒ ∠P + ∠Q + ∠R + ∠S = 360 °

⇒ 2∠R + 2∠R + ∠R + ∠R = 360 °

⇒ 6∠R = 360 °

⇒ ∠R =360/6

=60 °

∴ ∠P = ∠Q = 2 × 60 ° = 120 ° and

∠R = ∠S = 60 °

Hence, ∠P = 120 ° , ∠Q = 120 ° , ∠R = 60 ° and ∠S = 60 °.

Answer 2

angle P=120

angle Q=120

angle R=60

angle S= 60
