| Question | Answer |
| Arc | A part of the circumference. If the circle is split, the circumference is split into two arcs: the major arc is the arc that is longest while the minor arc is the shorter of the two. |
| Chord | A line running across a circle that joins two points on it. |
| Circumference | The perimeter of a circle. Equal to 2πr. |
| Diameter | A chord through the centre of the circle. |
| Radius | The distance from the centre of a circle to any point on its circumference. |
| Sector | A region of a circle between two radii and their cut-off arc. |
| Segment | A region in a circle between a chord and its cut-off arc. Like an arc, it is split into two: the major segment is the segment between the chord and the MAJOR arc while the minor segment is the segment between the chord and the MINOR arc. |
| Tangent | A line touching one point of the outside of a circle (the point of contact.) |
