Segment Lengths of the Circle
A circle may contain two or more segments. A segment is the region of a circle bounded by a chord and an arc. If the circle is divided into two segments, the bigger portion is called the major segment and the smaller portion is called the minor segment. The semi - circle is the biggest segment of any circle.
Answers:
- The lengths of the segments formed by intersecting two chords are equal.
- The segments formed by intersecting two secants at an external point are equal. A secant and a tangent that shares an endpoint outside the circle, then the product of the length of the secant segment and the length of its external segment equals the square of the length of the tangent segment.
Things to Remember:
- According to Intersecting Chords Theorem, "If two chords or secants intersect in the inside the circle, then the product of the lengths of the segments of one chord is equal to the product of the lengths of the segments of the other chord.
- According to Secant Secant Theorem, when two secant segments have a common endpoint outside the circle, the product of the measures of one secant segment and its external part is equal to the product of the measures of the other secant and its external part.
- According to Tangent Secant Theorem, if a secant segment and a tangent segment share an endpoint outside the circle, then the product of the length of the secant segment and the length of its external segment equals the square of the length of the tangent segment.
