Basic circle geometry

An arc is ...

• any connected part of the circle.

• a line that has endpoints on the circle.

• the distance around the circle.

• a line joining the centre of the circle to any point on the circumference circle.

A chord is ...

• any connected part of the circle.

• a line that has endpoints on the circle.

• the distance around the circle.

• a line joining the centre of the circle to any point on the circumference circle.

The circumference of a circle is ...

• any connected part of the circle.

• a line that has endpoints on the circle.

• the distance around the circle.

• a line joining the centre of the circle to any point on the circumference circle.

The radius of a circle is ...

• a line that has endpoints on the circle and passes through the centre of the circle.

• a line that has endpoints on the circle.

• a region of the circle bounded by two radii and an arc lying between the radii.

• a line joining the centre of the circle to any point on the circumference circle.
