प्रश्न
Draw a circle of radius 4.2 cm. Draw a tangent to the circle at point P on the circle without using the center of the circle
उत्तर
Steps of construction:
- Draw a circle of radius 4.2 cm and take any point P on it.
- Draw chord BP of any length and an inscribed ∠BAP of any measure.
- By taking A as a centre and any convenient distance on compass draw an arc intersecting the arms of ∠BAP in points P and Q.
- With P as a centre and the same distance in the compass, draw an arc intersecting the chord BP at point S.
- Taking radius equal to TQ and S as a centre, draw an arc intersecting the previously drawn arc. Name the point of intersection as R.
- Draw line RP.
Line RP is the required tangent to the circle.
