उत्तर
Steps of Construction:
- Draw AB = 6 cm.
- At A, draw a perpendicular to AB and cut AC = 4.5 cm on it. Join BC.
- Draw a perpendicular bisector of AC to get the midpoint O.
- With centre O and radius OC, draw the circle.
- Join BO.
- Draw a perpendicular bisector of BO to get the midpoint M.
- With centre M and radius MB (or MO), draw a circle cutting the given circle at P and Q.
- Join BP and BQ. These are the required tangents.
