Question

chords AB and CD intersects at point M in the interior of the same circle then prove that CM × BD = BM × AC​

Answer 1

Answer:

Intersecting chords theorem states that when two chords intersect each other inscale a circle, the product of their segments are equal also, diameter is the longest chord of the circle also now, draw a diameter of the circle passing through points P and M. it is the line XY as shown in the attachment

Length XY=2∗ radius =2∗13=26cm

MY=PY−PM=13−5=7cm

XM=XP+PM=13+5=18cm

By the intersecting chords theorem we have

CM∗PM=XM∗YM=18∗7=126

∴CM∗PM=126
