INTRODUCTION

Mathematics is often regarded as the language of the universe, providing a logical framework to understand patterns, structures, and relationships in the world around us. Among its many remarkable contributions, the Pythagorean Theorem stands out as a fundamental principle in geometry, offering a simple yet powerful method to calculate distances in right-angled triangles.

This theorem, attributed to the Greek mathematician Pythagoras, states that the square of the hypotenuse is equal to the sum of the squares of the other two sides. While it is a staple of school mathematics, its real-world applications extend far beyond textbooks. From construction and architecture to navigation, sports, and computer graphics, the Pythagorean Theorem plays a crucial role in solving practical problems. Engineers use it to design stable structures, surveyors rely on it for accurate land measurements, and even game developers apply it to create realistic animations.

By exploring these applications, this article highlights the relevance of the Pythagorean Theorem in everyday life, demonstrating how mathematical concepts shape our world in ways we often overlook

THEORETICAL BASIS

The Pythagorean Theorem is a fundamental concept in Euclidean geometry, stating that in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. Mathematically, it is expressed as:

$$c^2=a^2+b^2$$

where $c$ represents the hypotenuse, and $a$ and $b$ are the other two sides of the right-angled triangle. This theorem provides a foundational tool for measuring distances and analyzing spatial relationships, making it one of the most widely used principles in mathematics.

Historically, the theorem is attributed to the ancient Greek mathematician Pythagoras, although evidence suggests that similar concepts were known to earlier civilizations, such as the Babylonians and Egyptians. The theorem has been proven in multiple ways over centuries, using algebraic, geometric, and even trigonometric approaches, highlighting its fundamental importance in mathematical theory.

The Pythagorean Theorem is deeply connected to other mathematical areas, including trigonometry, coordinate geometry, and algebra. It serves as a basis for the distance formula in Cartesian coordinates, where the distance between two points $(x_1,y_1) \; and$$(x_2, y_2)$  is determined using the theorem. Additionally, it plays a crucial role in deriving trigonometric identities and solving real-world problems involving angles, heights, and distances.

Beyond theoretical mathematics, the theorem has vast practical applications in various disciplines. Architects and engineers use it to design and construct stable structures, while surveyors apply it for precise land measurements. In navigation, it helps determine the shortest path between two points, crucial for aviation and maritime travel. Furthermore, fields such as physics, sports analytics, and computer graphics rely on its principles for accurate calculations and visual modeling.

By understanding the theoretical foundation of the Pythagorean Theorem, we can appreciate its significance beyond academic study. Its applications in daily life and professional fields demonstrate how mathematical principles shape the world around us, making it an essential tool for problem-solving and innovation.
