Answer :

Steps to construct the required figure:

Step 1: Draw a circle with a bangle.

Step 2:Take two non- parallel chords as AB and CD of the circle.

Step 3: Draw the perpendicular bisector of these chords intersecting each other at O,which is the center of the circle made by bangle.

Step 4:Take a point P outside the circle and join OP.

Step 5: Mark the midpoint M of OP.

Step 6: Draw a circle with center as M and radius as MP=OM,which will intersect the first circle at R and Q.

Step 7:Join PQ and PR and hence we got the required tangents.

- Draw a circle of radius 6 cm. From a point 10 cm away from its centre, construct the pair of tangents to the circle and measure their lengths.
- Construct a tangent to a circle of radius 4 cm from a point on the concentric circle of radius 6 cm and measure its length. Also verify the measurement by actual calculation.
- Draw a circle of radius 3 cm. Take two points P and Q on one of its extended diameter each at a distance of 7 cm from its centre. Draw tangents to the circle from these two points P and Q.
- Draw a pair of tangents to a circle of radius 5 cm which are inclined to each other at an angle of 60°
- Draw a line segment AB of length 8 cm. Taking A as centre, draw a circle of radius 4 cm and taking B as centre, draw another circle of radius 3 cm. Construct tangents to each circle from the centre of the other circle.
- Let ABC be a right triangle in which AB = 6 cm, BC = 8 cm and \(\angle B=90° \) ;. BD is the perpendicular from B on AC. The circle through B, C, D is drawn. Construct the tangents from A to this circle.

- Q. 6 Let ABC be a right triangle in which AB = 6 cm, BC = 8 cm and \(\angle \) B = 90°. BD is the perpendicular from B on AC. The circle through B, C, D is drawn. Construct the tangents from A to this circle.
- Q.7 Draw a circle with the help of a bangle. Take a point outside the circle. Construct the pair of tangents from this point to the circle.
