प्रश्न

Draw the circle with centre C and radius 3.5 cm. Point B is at a distance 7 cm from the centre. Draw tangents to the circle from the point B.

उत्तर

1) Take centre C

2) Draw circle of radius 3.5 cm

3) Extend CA till CB where l(CB) = 7cm

4) Take distance more than half in compass and mark two arcs from the ends to line CB.

5) Now draw two more arcs above and below the line keeping the compass on these arcs.
