How to construct Tangents to circle if center of circle is not given?
If center of the circle is not given - Ex 11.2, 7

- And then finding the point of intersection of their perpendicular bisectors.
- Point of intersection of perpendicular bisectors is the center of circle
Then you could proceed as Construction 11.3 .
