Question

draw a circle of radius 4cm.from a point 7.5cm away from it's centre,construct the pair of tangents to the circle​

Answer 1

Answer:

pr and qr are the tangents

Answer 2

Answer:

Step-by-step explanation:

1. draw a circle of radius 4 cm and mark the center as O.

2. take a point P which is 7.5 cm away from the circle.

3. draw a perpendicular bisector of OP.

4.The point at which the perpendicular bisector cuts the line OP mark it as M.

5. Now draw a circle with radius OM.

6. This new circle with radius OM will cut the older circle at 2 points. Mark these points as T and Q.

7.now join OT and OQ .

8. OT and OQ are the required tangents.
