11. CONSTRUCTIONS
1. Draw a line segment of AB of length 7 cm. Taking A as centre draw a circle of radius 3 cm and taking B as a centre, draw another circle of radius 2 cm. Construct tangents to each circle from the centre of the other circle.
2. Draw a circle of radius of 3 cm. Take two points P and Q one of its extended diameter on both sides, each at a distance of 7 cm on opposite sides of its centre. Draw tangents to the circle from these points.
3. Draw two concentric circles of radii 3 cm and 5 cm. Taking a point on the outer circle, construct a pair of tangents to the inner circle.
4. Draw a circle of radius 4 cm. Draw two tangents to the circle inclined at angle of 60° to each other.
5. Draw a line segment of length 7 cm. Find a point P on it which divides it in the ratio 3 : 5.
6. Draw a line segment of length 5 cm and divide it in the ratio 3 : 7.
7. Let ABC be a right triangle in which AB = 6 cm. BC = 8 cm and ❮B = 90°. BD is the perpendicular from B on AC. The circle through B, C and D is drawn. construct the tangents From A to this circle.
8. Draw tangents to a circle of radius 6 cm from a point P at a distance of 10 cm from its centre.
