The circle

In geometry, the circle is the locus of points at the same distance from a given point.




An easier way to define such geometric figure is to say that it is a closed curved line with all points equally distant from the center.

The following shows an example:

Real life examples bicycle wheels, coins, such as dimes and pennies, CDs, and MP3 players.

A line segment joining two points on the figure is a chord.The following are examples of two chords

When a chord passes through the center,we call it a diameter. A diameter usually divides such figure into two equal halves. Each half is called a semi-circle

Half a diameter is called a radius.

In other words, 2 radii= diameter
