Consider the following for the next two (02) items that follow : AB is a diameter of a circle with centre O. Radius OP is perpendicular to AB. Let Q be any point on arc PB. What is ∠BAP equal to ?
Elementary MathematicsCircles
- A30°
- B40°
- C45°
- D60°
Explanation
OA and OP are both radii with OP ⊥ AB, so △OAP is right-angled and isosceles at O. Hence ∠OAP = ∠OPA = 45°, i.e. ∠BAP = 45°. This is option (c).
