A
circle is a two dimensional figure. In this figure all points are on the same
distance from centre. The distance from centre to edge is called the radius of
the circle. Diameter is the distance between two sides of the circle that goes
through the centre. Circle is one of the
important figure of geometry. Circle has many simple properties which help us
in many manner. Many

**geometry helper**starts with circle, according to these mathematician circle is a very easy topic which can be understand in quick steps. Some quick steps are given below, which helps you to understand the circle.

Centre:

Centre:

Centre
of the circle is the point inside the circle, all other points of the circle
are on same distance from the centre.

**Radius:**

The
distance from centre to any point on the circle is called the radius of the
circle. It is half of the diameter.

**Diameter:**

Diameter
is the distance between two sides of the circle that goes through the centre.
It is double of the radius.

**Circumference:**

All
round distance of the circle is called circumference.

**Area:**

It
is the region which is enclosed by the circle. Area of the circle is also
called surface area of the circle.

**Chord:**

Chord
is a line which link any two pints on circle.

**Tangent:**

Tangent
of a circle is a line that touches the circle exactly at one point.

**Secant:**

Secant
of a circle is a line that intersect the circle at two points.

These
are the basic properties of the circle. To learn more about circle
