Q2 of 20 Page 254

Draw a circle of radius 4.8 cm. Take a point on the circle. Draw the tangent at that point using the tangent-chord theorem.

Radius of the circle = 4.8 cm.


The steps for construction:


Step 1: With O as the center, draw a circle of radius 4.8cm.



Step 2: Take a point P on the circle.



Step 3: Through P, draw any chord PQ.



Step 4: Mark a point R distinct from P and Q on the circle so that P,Q and R are in counter clockwise direction.



Step 5: Join PR and QR.



Step 6: At P, construct ∠QPX = ∠PRQ



Step 7: Produce XP to Y get the required tangent line XY.



Thus, this is the resulting figure.
