If two tangents to the same circle intersect, their intersection point will be the same distance from each of the points of tangency.[br][br]Move points A,B, and C and observe how the lengths of segments CD and BD always remain the same.[br]
How are angles CDB and CAB related?[br]What do you think is the cause for this relationship?[br]
Is it possible for a circle to have three tangent lines that all intersect at the same point?[br]Explain your thinking.
