Question

Draw a circle of radius 3.6 cm Mark a point k on it. draw tangent to the circle passing through point k.​

Answer 1

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

2) Draw an angle of 90  from point O.

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

4) Now draw 90  from point Q

5) Draw 90  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

 

Now ∠AOB=90

 

and ∠APB=45

 

=∠AOB+∠APB=135
