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 .

Explanation

Dteps of construction :
(1) Draw a circle with centre O
(2) Take any point P on it
(3) draw ray OP
(4) Draw line `lbot"ray" OP` at point P
Line l is the required tangent to the circle
