Question

Draw a circle with center O and radius 4 cm. Draw any diameter AB of this circle. Construct tangents to the circle at each of the two end points of the diameter AB. 

Answer 1

Step 1: Draw a circle with center O and radius 4 cm. 

Step 2: Draw any diameter AOB of the circle. 

Step 3: At A, draw ∠OAX = 90 . Produce XA = Y 

Step 4: At B, draw ∠OBX' = 90 . Produce X' B to Y'.

Here, XAY and X'BY' are the tangents to the circle at the end points of the diameter AB
