Draw a circle of radius 3 cm. Mark a point P on the circle. Draw tangent to the circle through point P using the centre of the circle Analysis A circle of radius 3 cm can be drawn. Let the cemntre of the given circle be O and line l be the required tangent We know, converse of tangent theorem states that , 'A line perpendicular to radius at its outer end is tangent . therefore We construct perpendicular to radius OP at point, then line l is the required tangent .
