Question

draw a circle of radius 2.5cm. from a point P outside the circle, draw two tangents PQ and PR to the circle. verify that length of PQ and PR are equal​

Answer 1

Answer:

Steps of construction are as follows:-

1) Draw a circle of radius OQ= 3.5cm with centre at O.

2) Draw an angle of 90

0

from point O.

3) Let ray of angle intersect the circle at R.

4) Now draw 90

0

from point Q

5) Draw 90

0

at point R.

6) These two arcs meet each other, mark the point as P

PQ and PR are the two tangents inclined at angle of 45

0

Now ∠AOB=90

0

and ∠APB=45

0

=∠AOB+∠APB=135

0
