Question

6) Draw a circle of radius 3cm. From a point py
P7cm
away from centre draw the two tangents to the
circle - Measure the length of each tangent.​

Answer 1

Step-by-step explanation:

1. Draw a circle with O center radius 3cm
2. Mark a point P outside the circle such that OP= 7 cm
3. join OP. Draw the perpendicular bisector XY of OP. cutting OP at Q
4. Draw a circle with Q as center and radius PQ (or OQ) , to intersect the given circle st points T and T'.
5. join PT and PT'.

here

PT AND PT' ARE THE REQUIRED TANGENTS.

PT=PT'=6.3CM ( Approx)
