Steps of construction:

1. Draw a circle of radius 4 cm taking O as center.

2. Draw a diameter AB of this circle.

3. As we know that the tangents make an angle of 90° with the radius of the circle.

4. We draw ∠OAC = 90° at A. Produce CA to D. CD is the required tangent.

5. We draw ∠OBE = 90° at B. Produce EB to F. EF is the required tangent.
