Draw circle of radius 3.7 cm .

Draw a circle of radius 2.7 cm. Draw a tangent to the circle at any point on it.

Draw a circle of radius 2.6 cm. Draw a tangent to the circle from any point on the circle.

Draw a circle of radius 3.6 cm. Draw a tangent to the circle at any point on it without using the centre.

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 .
