Question

Length of Segment tangent blw the point & the given point of contant with the circle is called
the length of tangent from the to the circle​

Answer 1

Answer:

Length of the Tangent to a Circle. It is observed that |TC| is the radius of the circle, so |TC|2=g2+f2–c. This gives the length of the tangent from the point P(x1,y1) to the circle x2+y2+2gx+2fy+c=0.
