Draw a circle of radius 2.5 cm. Draw a tangent to the circle making an angle of 45^(@) with a line passing through the centre.

In the figure, O is the centre of the circle and LN is a diameter. If PQ is a tangent to the circle at K and angle KLN = 30^(@) , find angle PKL .

Solve any one of the following subquestions : Draw a circle with centre O and radius 3.5 cm . Locate a point Q in the plane of the circle such the tangent drawn from Q to the circle makes an angle of 30^(@) with OQ with the help of following steps. Consider the analytical figure as shown . Let OQ intersect the circle at A as hown and tangent from Q to the circle touch the circle at P then, (a) What will be the measure of angle AOP ? (b ) Thus by drawing the central angle AOP , P is located Construct tangent at P and locate Q. (c ) Measure OQ and relate it with OP

AB is a diameter of a circle. BP is a tangent to the circle at B . A straight line passing through A intersects BP at C and the circle at D . Prove that BC^(2)=ACxxCD .

Draw a pair of tangents to a circle which are inclined to each other at an angle of 30°. What should be the angle between two radii?

To draw a pair of tangents to a circle which are inclined to each other at an angle of 60° it is required to draw tangents at end point of these radii of the circle. The angle between them is

To draw a pair of tangents to a circle inclined to each other at an angle of 60^@ , it is required to draw the two radii of the circle intersecting at an angle of
