Answer:
The measure of AB will be 90°.
Step-by-step explanation:
In the given circle P we have to measure arc AB.
Since AC is a diameter and BP is perpendicular bisector of AC.
∠APB = 90°
Since this is the angle subtended at the center by inscribed arc AB .
Therefore, by definition length of arc AB will be equal to the ∠APB = 90°
The measure of AB will be 90°.
