PARTS OF A CIRCLE

The outside of the circle is called circumference The circumference is the distance around the circle.

The midpoint of a circle is centre

The line drawn from the centre to the circumference is … radius

The line drawn from one circumference through the centre to another circumference is … diameter radius The diameter cuts the circle in half!

A line that connects one point on the edge of the circle with another point on the circle is called …. chord The chord that passes through the centre of the circle is the diameter.

A segment ie. part of the circumference of the circle is called an ...
