Given below are the steps of construction of two tangents to the circle (without using the centre of the circle) of radius 4 cm from point P. Which of the following steps is INCORRECT? Steps of Construction Step I: Draw a circle of radius 4 cm and take a point P outside the circle and draw a secant PAB, intersecting the circle at A and B. Step II: Produce AP to C such that\[AP=CP\]. Draw a semicircle with CB as diameter. Step III: Draw PD 1 CB, intersecting the semicircle at D. With P as centre and PC as radius draw arcs to intersect the given circle at T and T. Step IV: Join PT and PT. Then, PT and PT are the required tangents.

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 Construction Step I: Draw a circle with centre O and radius\[2.5\text{ }cm\]. Step II: Draw a radius OA of this circle and produce it to B. Step III: Construct an angle \[\angle AOP\] equal to the complement of \[{{30}^{o}}\] i.e. equal to\[{{150}^{o}}\]. Step IV: Draw perpendicular to OP at P which intersects OA produced at Q. Clearly, PO is the desired tangent such that \[\angle OQP={{30}^{o}}\]
