Tangent and Secant Segments of a circle
Construct a radius on the circle and then construct a tangent to the circle that intersects the radius.
What is a tangent line?
What is the point called where the tangent line intersects the circle?
When a radius and a tangent line intersect at the point of tangency, what is created?
Construct two tangent lines that intersect at an exterior point.
What conclusion can be made if two tangent lines intersect at the same exterior point.
