The branch of mathematics that focuses on the study of angles and shapes is called Geometry. Geometry explores the properties and relationships of points, lines, surfaces, and solids. It includes various subfields, such as Euclidean geometry, which deals with flat spaces, and non-Euclidean geometries, which examine curved spaces. Geometric principles are fundamental in architecture, engineering, and many areas of science. Concepts such as congruence, similarity, and the Pythagorean theorem are crucial in understanding geometric relationships. Geometry not only aids in practical applications but also enhances problem-solving skills and logical reasoning in mathematical thinking.
