Steps of construction:
1) Draw a circle of radius ‘3’ cm from the centre “O” and pick a point ‘P’ on the circle. Join \(\overline{OP}\)
2) Now draw a perpendicular at the point ‘P’ to the line segment \(\overline{OP}\) such that XY ⊥ \(\overline{OP}\) .
3) Then \(\overline{XY}\) is the desired tangent at ‘P’ to the given circle.
