Euclidean Geometry
Euclidean geometry is a branch of mathematics that deals with the study of geometry based on the work of the ancient Greek mathematician Euclid. It is the study of properties, relationships, and measurements of figures in a two-dimensional space, such as points, lines, angles, polygons, and circles.
Euclidean geometry is characterized by a set of axioms or postulates, which are assumed to be true without proof, and from which all other geometric propositions and theorems are deduced. These axioms include principles such as the existence of a unique straight line between any two points, the ability to extend a line segment infinitely in either direction, and the ability to construct circles with any given center and radius.
In Euclidean geometry, various concepts and principles are explored, such as congruence (when two figures have the same size and shape), similarity (when two figures have the same shape but different sizes), parallel lines, perpendicular lines, symmetry, and transformations.
Euclidean geometry has important applications in various fields, including engineering, architecture, physics, and computer graphics. It provides a foundation for understanding and modeling the physical world, and its principles and theorems are used in problem-solving and proofs in various mathematical disciplines.
