WebOct 16, 2024 · A Proof Problem: Chords and Tangents. One thing we enjoy doing is guiding a student through the process of problem-solving. Here is a problem from August that illustrates how to think through a complicated geometrical proof. In particular, this uses some circle theorems involving chords, secants, and tangents, together with a bit of algebra. WebA secant is the name given to a line which extends through a circle cutting the circumference at two points. It occurs when two chords intersect outside of the circle. For …

Did you know?
WebIf two chords intersect, you can find a missing length using the intersecting chord theorem You can usually chose to solve the problem either using multiplication ( AP × PB = CP × PD) or using ratio ( AP : PD ≡ CP : PB) Keep track carefully of which distance is associated with each part of each chord 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.
