Tangents Intersect at a Point
Tangents Intersect at a Point
1. What kind of lines are CD and BD?
2. Drag points C and B. What do you notice about CD and BD?
3. Write a conclusion about two tangent lines that intersect at a point outside of the circle?
If CD is 10, what is the length of BD?
If BD is 6.3, what is the length of CD?
