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. |
A) Only Step I
B) Both Step I and Step II
C) Only Step III
D) Both Step II and Step IV
Correct Answer: C
Solution :
Steps of Construction Step I: Draw a circle of radius 4 cm and take a point P outside it. Through P draw a secant PAB to intersect the circle at A and B. Step II: Produce AP to a point C such that\[AP=CP\]. Draw a semicircle with CB as diameter. Step III: Draw \[PD\bot CB\]intersecting the semicircle at D. With P as centre and PD as radius draw arcs to intersect the circle at 7" and T'. Step IV: Join PT and PT. Then, PT and PT are the required tangents.You need to login to perform this action.
