Contents
Theorem:
There are three unique cases for this theorem. Each case expresses the relationship between the length of line segments that pass through a common point and touch a circle in at least one point.
Case 1 (Inside the Circle):
If two chords 
and 
intersect at a point 
within a circle, then 
Case 2 (Outside the Circle):
[b]lassic Configuration[/b]
[b]Tangent Line[/b]
Normal Configuration
Tangent Line
Case 3 (On the Border/Useless Case):
