Question

draw a circle of radius 4 cm and a pair of tangents on it from a point 6cm away from centre
​

Answer 1

Answer:

ANSWER

Steps of construction:

1) Draw a circle of radius 4cm with centre O

2) Take any point P on the circle and draw a chord PQ of length 6cm.

3)From P cut the line PQ at 3cm (mid-point).

4) Join O and the midpoint and extend this line till it intercepts the circle at R.

5) OR is the radius perpendicular to chord PQ.

6)Draw perpendicular lines to PQ at P and Q and to OR at R.

7) The perpendicular lines drawn at P, Q and R are the required tangents.
