| In one circle, chords AC and BE are drawn, intersecting at point M. Find the length of the segment AM if CM = 2, BM = 6, EM = 4.
At the point of intersection, the chord AC is divided into segments AM and CM, and the chord BE is divided into segments BM and CM. There is a well-known theorem that when chords intersect, the products of their constituent segments must be equal:
AM * CM = BM * EM;
AM = (BM * EM) / CM = (6 * 4) / 2 = 12.
Answer: AM = 12.
