Draw a circle of radius 4cm. Take a point P outside the circle. Without using the centre of the circle, draw two tangents to the circle from point P and justify your answer.

Expert Answer:

dear student,
when the center is not given, you can  draw any two non parallel chords.construct their perpendicular bisectors.The point of intersection of these perpendicular bisectors is actually the center of the circle.
once the center is located, remaining procedure is the same as the case where you have to construct tangents for a circle whose center is given.
hope this clarifies your doubt.
