The word “polygon” is derived from Greek for “many angles”. 4.2: 2-D Geometry A polygon is a closed, 2-dimensional shape, with edges(sides) are straight lines.There are two types of Euclidean geometry: plane geometry, which is two-dimensional Euclidean geometry, and solid geometry, which is three-dimensional Euclidean geometry. 4.1: Euclidean geometry Euclidean geometry, sometimes called parabolic geometry, is a geometry that follows a set of propositions that are based on Euclid's five postulates.they observed that in learning geometry, students seem to progress through the following sequence: recognition, analysis, relationship, deduction (the study of geometry as a mathematical system), and axiomatic.

This theory was developed in the late 1950s by two Netherlands mathematics teachers. Research in teaching and learning of geometry has given strong support to the van Hiele theory. The first axiomatic system was developed by Euclid in his books called 'Elements'. They not only asked “how” and “what” but also asked, “why.” At the foundations of any theory, there are truths, which are taken for granted and can't be proved or disproved. The study of geometry was carried on by the Greeks Thales, Pythagoras (550 BC), Plato, and Euclid ( father of geometry, 300 BC). Egyptians were among the first people to use geometry to survey the land. In Greek, 'geo' means earth, and 'metron” means measure.
