Draw a tangent to the circle from the point \(P\) having radius \(3.6 \ cm\), and centre at \(O\). Point \(P\) is at a distance \(7.2 \ cm\) from the centre.
Construction:
Step 1: With \(O\) as the centre, draw .
Step 2: Draw .
Step 3: Draw , which cuts \(OP\) at \(M\).
Step 4: With \(M\) as centre and \(MO\) as radius, draw .
Step 5: Join \(AP\) and \(BP\). \(AP\) and \(BP\) are the required tangents. Thus, length of the tangents are \(PA = PB = \) \(\ cm\).
