Draw a circle of radius 4 cm. Take a poin P outside the circle. Without using the centre of the circle, draw two tangents to the circle from point P. |
Answer» Solution :Steps of Construction : 1. Draw a line segment 4 cm. 2. Take a point P outside the circle and draw a SECANT PAB, intersecting the circle at A and B. 3. Produce AP to C such that AP=CP. 4. Draw a semi- circle with CB as diameter. 5. Draw PD `bot` CB, intesecting the semi- circle at D. 6. With P as CENTRE and PD as RADIUS draw arcs to intersect the GIVEN circle at T and T'. 7. Join PT and PT'. Then, PT and PT' are the required tangents. ![]() |
