Interaction between Line and Circle

The tangent to a circle is a special case of the secant when the two end points of its corresponding chord coincide. (Yes/No)

Every normal of a circle passes through center of the circle.

What is chord of a circle?

A line that intersects a circle at a minimum of two distinct.

There will be no point of intersection if a line does not touch the circle at all

When a circle and a line are in a plane, they can have only two points of intersection.
 

At any point on a circle there can be one and only one tangent.

The tangent to a circle is a special case of the _____ when the two end points of its corresponding chord coincide.

Find radius of circle with centre O. If $AO\perp OC$.

Chords MN and RS of a circle intersect at P outside the circle. If $PN=3 cm, MN= 5 cm, PR = 2 cm$. Then the value of SR is equal to.


 

A straight line which passes through two points on a circle is

The lengths of two parallel chords on one side of the centre of a circle are $6$ cm and $8$ cm. If they are at a distance of $1$ cm, then the diameter of the circle will be

In the given figure, the diameter of two wheels have measured $2 \mathrm{cm}$ and$4 \mathrm{cm}$. The length of the belts $AD$ and $BC$ that pass around the wheels, if it is given that belts cross each other at right angles is $k \mathrm{cm}$. Find the value of $k$.
