WebRecall that the intersecting chords theorem tell us that if chord 𝐴 𝐵 and chord 𝐶 𝐷 of the same circle intersect at point 𝐸, 𝐴 𝐸 × 𝐸 𝐵 = 𝐶 𝐸 × 𝐸 𝐷. We are given 𝐸 𝐶 = 4, 𝐸 𝐷 = 1 5, and 𝐸 𝐵 = 6, so we can substitute these values into this formula, where 𝐶 𝐸 = 𝐸 𝐶 and 𝐴 𝐸 = 𝐸 𝐴, to obtain 𝐸 𝐴 × 6 = 4 × 1 5 6 𝐸 𝐴 = 6 0 𝐸 𝐴 = 1 0. WebIntersecting Chords (Finding Angle Measure) If two chords intersect inside a circle, then the measure of the angle formed is one half the sum of the measure of the arcs intercepted by the angle and its vertical angle .
