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.
