Draw a circle of radius 3 cm. Draw a tangent to the circle making an angle of 30∘ with a line passing through the centre.
Steps Of construction:
Step 1: Draw a circle with center O and radius 3 cm.
Step 2: Draw radius OA and produce it to B.
Step 3: Make angle AOP = 60.
Step 4: Draw PQ perpendicular to OP, meeting OB at Q.
Step 5: Then, PQ is the desired tangent, such that angle OQP = 30
