Question

what happens to the inscribed angle when point b is moved along the arc? the inscribed angle changes; the inscribed angle becomes zero; the inscribed angle doubles; the inscribed angle remains the same

Explanation:

This is based on the inscribed angle theorem, which states that all inscribed angles subtended by the same arc of a circle are congruent (equal in measure). Moving point B along the arc does not change the arc that the inscribed angle subtends, so the angle's measure stays constant.

Answer:

The inscribed angle remains the same
