Question

Draw a circle of radius 4 cm .construct a pair of tangents to it from a point 8 cm away from its centre.

Answer 1

Step-by-step explanation:

1. draw a circle with centre 'O' of radius 4cm.
2. take a point 'P' 8 cm away from its centre.
3. join OP. draw perpendicular bisector of OP.
4. name the point of intersection as M.
5. taking MP as radius and M as centre draw another circle.
6. name the point A and B where the smaller circle intersects the larger circle respectively.
7. PA and PB are the required tangents.

Answer 2

Step-by-step explanation:

1.Draw a line segment of op=8cm,with o as centre and draw a circle of radius 4cm.

2.Draw perpendicular of op at M.

Draw another circle centre as M.

3.Mark the points of intersection and of both rhe circles as A and B

4.join points PAand point PB.
