- The Pythagoras theorem is defined as: a² + b² = c².
- Here, 'c' represents the length of the hypotenuse, while 'a' and 'b' represent the lengths of the other two sides of a right triangle.
- This relationship holds true for all right triangles, providing a method to calculate unknown side lengths.
- To utilize the Pythagoras theorem effectively, one must identify which sides of the triangle are known.
- If 'a' and 'b' are known, the hypotenuse 'c' can be calculated as c = √(a² + b²).
- Conversely, if 'c' is known and one side is known, the other side can be found using a = √(c² - b²) or b = √(c² - a²).
- In practical scenarios, the theorem can be applied to real-world problems such as architecture, construction, and navigation, where determining distances is crucial.
