Question

Draw a tangent to a given circle with center O from Point R outside the circle. how many can be drawn to a circle from that point? Hint:the distance of two points to the point of contact is the same.​

Answer 1

Answer:

No tangent line can be drawn through a point within a circle, since any such line must be a secant line. However, two tangent lines can be drawn to a circle from a point P outside of the circle.
