Pohl's theorem

Pohl's theorem is a concept in geometry that relates how two lines intersect inside a circle. It states that if two chords intersect within a circle, then the products of the segments they create are equal. When two chords cross, the length of one segment on the first chord times the other segment on that chord equals the product of the two segments on the second chord. This theorem helps us understand relationships within circle geometry and can be used to find missing segment lengths or prove certain points are colinear, all based on crossing chords inside a circle.
