Which of the following steps of construction is INCORRECT while drawing a tangent to a circle of radius 5 cm and making an angle of 30° with a line passing through the centre.Steps of ConstructionStep I : Draw a circle with centre O and radius 2.5 cm.Step II : Draw a radius OA of this circle and produce it to B.Step III : Construct an angle ∠AOP equal to the complement of 30° i.e. equal to 150°.Step IV : Draw perpendicular to OP at P which intersects OA produced at Q.Clearly, PQ is the desired tangent such that ∠OQP = 30°(A) Both I and III(B) Only III(C) Both III and IV(D) Only I

Answer»

The correct option is: (A) Both I and III

Explanation:

Step I and III are incorrect. Draw a circle with centre O and radius 5 cm and construct AOP equal to complement of 30° i.e., equal to 60° are correct steps.
