Draw a circle with center C and radius 3.2 cm. Draw a tangent to the circle from point P at a distance of 7.5 cm from the center of the circle
उत्तर
Steps of construction:
- With centre C, draw a circle of radius 3.2 cm
- Take point P such that CP = 7.5 cm
- Draw the perpendicular bisector of seg CP. It intersects CP in point M.
- With M as centre and radius equal to CM, draw an arc intersecting the circle in points Q.
- Draw ray PQ.
Ray PQ is the required tangent to the circle.
