What is Geometrical Terms?
The agreed vocabulary of Cambridge IGCSE Mathematics 0580 geometry: the names and defining properties of lines, angles, triangles, quadrilaterals, polygons, solids and the parts of a circle, listed separately for the Core route (C4.1) and the Extended route (E4.1). A defining property is the minimum condition a shape must satisfy to be given that name, and it is the only thing a name entitles you to assume about a figure.
This definition is part of the Geometry chapter in Cambridge IGCSE Mathematics.
