Parts of a Circle
Cards in this deck (8)

- 2ChordA line running across a circle that joins two points on it.
- 3CircumferenceThe perimeter of a circle. Equal to 2πr.
- 4DiameterA chord through the centre of the circle.
- 5RadiusThe distance from the centre of a circle to any point on its circumference.
- 6SectorA region of a circle between two radii and their cut-off arc.
- 7SegmentA 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.
