The point where a secant meets a circle is known as its point of contact.

The chord which passes through the centre of a circle is known as its diameter.

At the point of contact, radius and tangent are perpendicular to each other.

If the radius of a circle is 4 cm then a point which is at 4.5 cm from the centre will lie inside the circle.

All radii of a circle are equal.

A circle is a set of lines that are equidistant from a fixed point.

The set of all the points which lie inside a circle is known as exterior of the circle.

Only one tangent can be drawn through a point on the circle.

An arc is a part of a circle between any two points on the circle.

The diameter of a circle is 10.6 cm. What is its radius?

Triangle PQR is drawn inside a circle such that its three vertices touch the boundary of the circle. If PR is the diameter of the circle, what is the measure of $$\angle$$Q?

What will be the diameter of a circle of radius 8 cm?

Which of the following intersects a circle at two distinct points?
