# Intersecting Chords

Products of segments of intersecting chords are equal

### Intersecting Chords Theorem

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.

$N \cdot M = L \cdot M$
