# Pythagorean Theorem

Pythagorean Theorem is an iconic equation that has been used for millennia, and to this day, it remains the cornerstone of geometry studies. It states that in any right-angled triangle, the square of the hypotenuse (longest side) can be found by summing up the squares of the other two sides.

This beautiful equation continues to intrigue math enthusiasts by showcasing its simplicity yet effectiveness; if you have a triangle, then the Pythagorean Theorem will help with its calculation. Every beginning geometry student must understand this Theorem, as it forms the basis of their further studies.
