9.2.2 FINDING LENGTH OF THE TANGENT
Can we find the length of the tangent to a circle from a given point? Is the lengt
tangents from a given point to the circle the same? Let us examine this.
Find the length of the tangent to a circle with centre 'O' and radius=6 cm.fr​

Answer 1

Step-by-step explanation:

2STEPS 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 ∠OMN=90

∘

MN is the required tangent.
