A figure with four equal sides A set of points equidistant from a fixed point A straight line A polygonQuestion 1 of 202. The fixed point of a circle is called the: Radius Diameter Centre ChordQuestion 2 of 203. The distance from the centre to any point on the circle is called: Diameter Radius Arc ChordQuestion 3 of 204. A line segment joining two points on a circle is called: Radius Diameter Chord ArcQuestion 4 of 205. A chord passing through the centre is called: Radius Diameter Arc SectorQuestion 5 of 206.
