Question Video: The Definition of a Circular Segment Mathematics • First Year of Secondary School

Video Transcript

What is the definition of a circular segment? Is it (A) a region of a circle bounded by an arc and a chord passing through the end points of the arc? (B) A region of a circle bounded by two radii and an arc. (C) A region of a circle bounded by a chord and a central angle subtended by that arc. (D) A region of a circle bounded between two chords and two arcs. Or (E) an arc which is half of the circumference.

The circle shown has been split into two segments. The smaller part of the circle is known as the minor segment. The larger part is known as the major segment. Both of these segments are bounded by an arc. They are also bounded by a common chord. This means that the correct definition is option (A). A circular segment is a region of a circle bounded by an arc and a chord passing through the end points of the arc. In our diagram, we have a minor segment in orange and a major segment in pink.
