Step 1: Using your compass and measuring a length 5.4 cm, draw a full circle, centered at a point P . The size of the opening of the compass is the radius of the circle (5.4 cm)

Step 2: Make a point Q (an external point) at a distance 9 cm from the center of the circle

Step 3: Join the points P an Q together to form the line PQ

Step 4: Bisect the line PQ on both sides, and draw a straight line joining the two bisections. The straight line will intersect the line PQ at the midpoint R

Step 5: Using R as the midpoint, draw another circle. The new circle will touch the original circle at two opposite points namely M and N

Step 6: Join the lines QM and QN. The lines QN and QM give the tangents to the circle
