Question

38) Draw a circle of radius 6 cm.
from a point 10 cm away from the
Centre. construct the pair of tangents to the circle and measure their lengths.

find numble (38) and (39) please paper solution in detail ​

Answer 1

Step-by-step explanation:

Draw a circle of radius 6 cm.

2. Mark a point P at a distance 10 cm from the centre O.

3. Here OP = 10 cm, draw perpendicular bisector of OP, which intersects OP at O’.

4. Take O’ as centre, draw a circle of radius O’O, which passes through O and P and intersects the previous circle at points T and Q.

5. Join PT and PQ, measure them, these are the required tangents.
