Pythagoras Theorem: An Overview
The Pythagorean theorem is a fundamental principle in geometry, specifically concerning right-angled triangles. It establishes a relationship between the lengths of the sides of a triangle.
Formula
The theorem states that in a right-angled triangle:

• a: length of one leg
• b: length of the other leg
• c: length of the hypotenuse (the side opposite the right angle)

The relationship is expressed as:
c² = a² + b²
Components of the Theorem
1. Right-Angled Triangle
A triangle where one angle measures 90 degrees.
2. Legs and Hypotenuse
The two shorter sides are referred to as legs (a and b), while the longest side is the hypotenuse (c).
3. Square Relationships
The theorem describes how the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Applications
The Pythagorean theorem has various applications, including:

• Construction: Ensuring structures are level and square.
• Navigation: Calculating the shortest distance between two points.
• Physics: Analyzing forces and vectors in two dimensions.

Conclusion
Understanding the Pythagorean theorem is essential, not just in mathematics but also in various practical fields. It provides a basis for solving problems related to distances and angles, making it a crucial concept in both academia and industry.
