We can draw ………… tangents to a given circle .

How can you draw the tangent to a circle at a given point when the centre of the circle is not known?

In the below figure which are tangents to the given circles ?

Draw a circle of radius 3 cm . Take a point 'P' at a distance of 5 cm , from the centre of the circle . From P , draw 2 tangents to the circle.

Draw a circle of radius 4 cm and draw a pair of tangent to the circle, which are intersecting each other 6 cm away from the centre.

Draw a circle of radius 5 cm . From a point 8 cm away from its centre , construct a pair of tangents to the circle . Find the lengths of tangents .

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

Draw a Circle of radius 4 cm . From a poit 7.5 cm away from its centre , construct the pair of tangents to the circle .

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?

Statement(A): Diameter is the longest chord in the circle Statement(B):We can draw infinite no of chords in a circle
