Question

How can you draw a tangent to a circle in a given point when the centre of the circle is not known?

Answer 1

STEPS TO FOLLOW:

Given the circle of unknown center.

Draw 2 chords of unknown length AB and AD.

Draw perpendicular bisectors of AB and AD. Mark the point of intersection of perpendicular bisectors as C.

From point C, draw a radius OM.

At point M, make an $\angle OMN={90}^{\circ }$

MN is the required tangent.
