How do the radius and diameter compare to each other?

Construct a secant for the given circle.

Construct a tangent for the given circle and a radius that intersects at the point of tangency.

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.
