Question

Draw a circle with centre 0. Take any point A on it and construct tangent at A
using the centre of the circle.​

Answer 1

Step 1: Draw a circle with any radius and mark any point A on it.

Step 2: draw chord AB and an inscribed ∠BCA

Step 3: With the centre C and any convenient radius draw an arc intersecting the sides of ∠ACB in points M and N .

Step 4: Using the same radius and centre A , draw an arc intersecting the chord AB at point O

Step 5: : Taking the radius equal to d(MN) and Centre O, draw an arc intersecting the arc drawn step 4 . Suppose D be point of intersection of these arcs.Draw line AD.
