Draw a circle, identify a point on it. Cut arcs on the circle with the length or the radius in succession. Hoe many parts can the circle be divided into ? Give reasons.

Draw a circle, Identify a point on it. Cut arcs on the circle with the length of the radius in succession. How many parts can the circle be divided into? Give reason.

Which part of a circle divides it into two semicircles?

How many radii can we draw in a circle ?

Draw a circle with 5 cm radius and construst a pair of tangents to the circle .

Draw tangent to a given circle with Centre O from a point 'R' outside the circle. How many tangents can be drawn to the circle from the point ?

The common point of the tangent and the circle is called the point of contact and the tangents is said to touch the circle at the common point. Observe the tangents to the circle in the figures given below. How many tangents can you obtain to the circle.in all?See the points of contact. Draw radii from the points of contact. Do you see any thing special about the angle between the tangents and radii at the points of contact. All appear to be perpendicular to the corresponding tangents. How many tangents can you draw to a circle at a point?

A point P is 25 cm from the centre O of the circle. The length of the tangent drawn from P to the circle is 24 cm. Find the radius of the circle.
