How many radii can we draw in a circle ?

Draw a circle on a paper and cut it along its edge. Fold it into half and again fold it to one fourth to make folding marks as shown .You will observe a point in the middle. Mark this O. This is the centre of the circle. You can also indicate its radius.How many radii can you draw in a circle ?.

How many tangents can be draw to a circle from a point on the same circle . Why ?

How many rays can we draw from a given point

How many tangnets can you draw to a circle , which are parallel to each other ?

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?

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 ?
