It is framed with properties of space that are related with distance, shape, size, and relative position of figures.
Invention: Classic geometry used a compass and straightedge constructions. Euclid revolutionized the subject, who introduced what we still use today, mathematical rigor and the axiomatic method.
Principles: Geometry covers points, lines, planes, angles, parallel lines, triangles, similarity, trigonometry, quadrilaterals, transformations, and circles and area. It can be applied to many professions.
