- 1. Euclidean geometry is a mathematical system attributed to the ancient Greek mathematician Euclid, which is based on a set of axioms and definitions regarding points, lines, shapes, and dimensions in two- and three-dimensional space. It is characterized by the use of the ruler and compass as fundamental tools for constructing geometric figures and deriving mathematical relationships. Euclidean geometry explores concepts such as congruence, similarity, parallelism, and perpendicularity, and provides a framework for the study of geometric problems and proofs. The principles of Euclidean geometry have had a profound impact on mathematics and science, serving as the foundation for various branches of geometry and influencing areas such as physics, engineering, and architecture.
