1. Answer:

   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.

   Here line AD is the required tangent to the circle.
