Geometrical Terms

What is Geometrical Terms?

The agreed vocabulary of Cambridge O Level Mathematics geometry: the names and defining properties of lines, angles, triangles, quadrilaterals, polygons, solids and the parts of a circle. 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 O Level Mathematics (Syllabus D).
