What is the intersecting chord theorem What does it help you do?
If two chords intersect in a circle , then the products of the measures of the segments of the chords are equal.
How do you prove that a chord is equal?
2) Equal-chords of congruent circles are equidistant from the corresponding centers. If two circles are congruent and AB = CD then OL = PM….Equal Chords of a Circle.
| Statements | Reasons |
|---|---|
| 7) AB = CD | 7) Chords are equidistant from center O |
How do you solve intersecting Secants?
If two secant segments are drawn to a circle from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment.
What is the relationship between intersecting chords?
The intersecting chords theorem or just the chord theorem is a statement in elementary geometry that describes a relation of the four line segments created by two intersecting chords within a circle. It states that the products of the lengths of the line segments on each chord are equal.
What conclusion can you make about the relationship that exists among segments formed by intersecting chords of a circle?
When two chords intersect each other inside a circle, the products of their segments are equal.
Why are intersecting chords equal?
When two chords intersect each other inside a circle, the products of their segments are equal. One chord is cut into two line segments A and B. The other into the segments C and D. This theorem states that A×B is always equal to C×D no matter where the chords are.
What is the rule of chords?
Chords are equidistant from the center if and only if their lengths are equal. Equal chords are subtended by equal angles from the center of the circle. A chord that passes through the center of a circle is called a diameter and is the longest chord of that specific circle.

What are intersecting chords?
The intersecting chords theorem or just chord theorem is a statement in elementary geometry that describes a relation of the four line segments created by two intersecting chords in a circle. It states that the products of the lengths of the line segments on each chord are equal.
Are corresponding chords of two congruent arcs are equal?
Congruent arc : Two arcs of a circle are said to be congruent if and only if they have the same degree of measure. Some results on congruent Arc and chords. 1) If two arcs of a circle are congruent, then corresponding chords are equal. If arc PQ = arc RS then chord PQ = chord RS. Converse of the above is also true.
What is circle of fifths progression?
A circle of fifths progression is one where the roots of the chords are related to each other specifically by ascending 4ths or descending 5ths. Circle of fifths progressions are considered to be harmonically very strong, in the sense that they pull our ear toward one chord being the tonic, or key chord.
What is tangent chord theorem?
The alternate segment theorem (also known as the tangent-chord theorem) states that in any circle, the angle between a chord and a tangent through one of the end points of the chord is equal to the angle in the alternate segment. In the above diagram, the angles of the same color are equal to each other.
