Question
What special name can be given to a quadrilateral PQRS if the ∠P + ∠S =180°?
Solution
The special name given to a quadrilateral PQRS if ∠P + ∠S = 180° is a Cyclic Quadrilateral.
Here's why:
- In a quadrilateral, the sum of all interior angles is 360°.
- If ∠P + ∠S = 180°, it means that the opposite angles of the quadrilateral are supplementary (add up to 180°).
- This is a property of a Cyclic Quadrilateral, where the opposite angles are supplementary.
- Therefore, if ∠P + ∠S = 180°, the quadrilateral PQRS can be called a Cyclic Quadrilateral.
