👉 The closest math to a fundamental concept in mathematics is often found in the realm of geometry, specifically in Euclidean geometry. This branch of mathematics deals with points, lines, angles, surfaces, solids, and higher-dimensional analogs, providing the foundational tools for understanding spatial relationships. Central to this area are basic principles like the Pythagorean theorem, which describes the relationship between the sides of a right-angled triangle (a² + b² = c²), and properties of similar figures, which allow us to compare shapes regardless of their size. These concepts form the bedrock for more advanced mathematical theories and practical applications in fields like architecture, engineering, and physics.
