Question Analysis

This question focuses on identifying the type of angle in a circle, specifically testing the understanding of the difference between angles and arcs in a circular context.

Key Concept Explanation

Semi - circle Arc: An arc that is exactly half of the circle's circumference, measuring 180 degrees. It is a curved part of the circle, not an angle.

Central Angle: An angle whose vertex is at the center of the circle ( in this case), and whose sides are radii ( and ).

Major Arc: An arc that is greater than a semi - circle, measuring more than 180 degrees. It is a curved part of the circle, not an angle.

Minor Arc: An arc that is less than a semi - circle, measuring less than 180 degrees. It is also a curved part of the circle, not an angle.

Step - by - Step Solution

1. Observe the angle : The vertex of the angle is at the center  of the circle, and the two sides
