Question 28 (OR 1st question) Draw a circle of radius 4 cm. From the point 7 cm away from its centre, construct the pair of tangents to the circle.
Steps of construction
Draw a circle of radius 4 cm
Draw point P, 7 cm away from center
1 mark
for drawing circle
3. Join PO.
Make perpendicular bisector of PO
Let M be the midpoint of PO.
4. Taking M as centre and MO as radius,
draw a circle.
5. Let it intersect the given circle at points Q and R.
6. Join PQ and PR.
∴ PQ and PR are the required two tangents.
