In geometry, a three-dimensional figure with six identical, square faces. Adjoining edges and faces are at right angles. In number and algebra, the result of multiplying to power of three, n3 is read as ‘n cubed’ or ‘n to the power of three’ Example: Written 23, the cube of 2 is (2 x 2 x 2) = 8. cube number.

Mrs Jones bought 12 Kilos of potatoes today. Centre Another word for 'middle'. The centre of a circle is the point which is the same distance from all points on the circumference. Centre of Rotation A point about which a shape is rotated. The centre of rotation may be on the shape being rotated (perhaps even the centre of the shape) or it may be of...

h Graph A way of showing a relationship on a diagram. The most common types of graph are block graphs, line graphs and pie charts. www.mathsphere.co.uk Grid A sequence of (normally) horizontal and vertical intersecting lines used to draw patterns or graphs. Heptagon A polygon with seven sides. Hexagon A polygon with six sides.
www.mathsphere.co.uk Inscribed circle A circle drawn inside a polygon (normally a triangle) so that it just touches each of the sides of the polygon. In a triangle the centre of this circle is obtained by bisecting each angle and putting the compass point at the place where the three bisectors meet.
