If two chords intersect inside a circle, then the product of the lengths of the segments of one chord equals the product of the lengths of the segments of the other chord. N ⋅ O = L ⋅ M. …
Intersecting chords theorem outside circle
Did you know?
WebL is 1/2 the chord length. r is the same radius you already found. So we already know 2 sides for this triangle and just need to solve for L and double it to get the second chord length. r^2=a^2+L^2. L^2=r^2-a^2 = 35.23^2-17^2. L= sqrt (35.23^2-17^2) L=30.85. Just double that to get the length of the second cord. WebA secant segment is a segment with one endpoint on a circle, one endpoint outside the circle, and one point between these points that intersects the circle. Three theorems exist concerning the above segments. Theorem 1 PARGRAPH When two chords of the same circle intersect, each chord is divided into two segments by the other chord.
