Example: If AP = 4, CP = 5, and PB = 10, we can find the length of chord CD as follows, 5 · PD = 4 · 10 5 · PD = 40 PD = 8 Since CD = CP + PD, CD = 5 + 8 = 13 Angles of intersecting chords theorem The angles formed by intersecting chords inside a circle can be determined using the arcs they intercept. … See more If two chords intersect inside a circle, four angles are formed. Additionally, the endpoints of the chords divide the circle into arcs. In the diagram above, chords AB and CD intersect at P forming 2 pairs of congruent vertical … See more If two chords intersect inside of a circle, the product of the lengths of their respective line segments is equal. In the diagram above, if … See more An inscribed angle for a circle is formed when two chords intersect at one of their endpoints on the circle. In the diagram above, chords AB … See more The angles formed by intersecting chords inside a circle can be determined using the arcs they intercept. Referencing the same diagram used above: See more WebChords Of A Circle Theorems Example 1: A chord of a circle is equal to its radius. Find the angle subtended by this chord at a point in the major segment.

WebLines. A line that "just touches" the circle as it passes by is called a Tangent. A line that cuts the circle at two points is called a Secant. A line segment that goes from one point to another on the circle's circumference is … A chord of a circle is a straight line segment whose endpoints both lie on a circular arc. If a chord were to be extended infinitely on both directions into a line, the object is a secant line. More generally, a chord is a line segment joining two points on any curve, for instance, an ellipse. A chord that passes through a circle's center point is the circle's diameter. The word chord is from the Latin c… sage 300 credit card payment processing
