Objective:
To verify that the angles in the same segment of a circle are equal.
Basic Concepts and Facts:
Segments of a Circle :
- A chord of a circle divides the circle into two regions,called the segments of the circle.
- The minor segment is the region bounded by the chord and the minor arc intercepted by the chord.
- The major segment is the region bounded by the chord and the major arc intercepted by the chord.

Angles in Different Segments :
In the following diagram, ∠APB is in the major segment and ∠AQB is in the minor segment. So, we say that ∠APB and ∠AQB are in different segments.
Angles in the Same Segment :
In the following diagram, ∠PRQ and ∠PSQ are in the major segment. So, we say that ∠PRQ and ∠PSQ are in the same segment.
