Question

The number of tangent that can be drawn to a cricle at a point on the circle is

Answer 1

Answer:

Two tangent are drawn

Answer 2

Answer:

) The number of tangent (s) that can be drawn to a circle at a point on the circle is 1. 

SInce, The point lies on a circle .

The Equation of Tangent at point P(x_{1},y_{1})P(x1,y1) on the circle

x^{2} + y^{2} +2gx+2fy +c=0x2+y2+2gx+2fy+c=0

is given by: 

  

\boxed{xx_{1}+yy_{1}+g(x+x_{1})+f(y+y_{1}) + c =0}xx1+yy1+g(x+x1)+f(y+y1)+c=0

Therefore, There exists only one equation of Tangent for a given point P on circle.
