Circumference :Circumference Around the circle
Arc :Arc Part of the circumference
Semicircle :Semicircle Half of a full circle
Centre :Centre The point inside the circle which is equal distant from all points on the circle (equidistant).
Radius :Radius An interval drawn from the centre of the circle to the circumference
Diameter :Diameter An interval passing the centre, which divides the circle in half.
(diameter = 2 x radius)
Sector :Sector An area cut off by two radii
Chord :Chord An interval joining two points on the circumference, but not passing through the centre
Tangent :Tangent A line on the exterior of the circle that touches the circumference at one point
Minor segment :Minor segment The smaller of the two regions inside a circle bounded by the circle and a chord
Major segment :Major segment The larger of the two regions inside a circle bounded by the circle and a chord
