Explains about the relationship between the number of tangents that can be drawn from a given point to a given circle, and the position of the point with respect to the circle

Lesson Outcomes

• At the end of this lesson, the student will be able to:
• Define circle, centre and tangent
• Learn the proof that two tangent lines can be drawn to a circle from a point outside of the circle
• Learn the proof that the lengths of tangents drawn from an external point to a circle are equal
