Pacioli's Theorem

Pacioli's Theorem states that in any right-angled triangle, the area of the square built on the hypotenuse (the longest side) equals the sum of the areas of the squares built on the other two legs (the shorter sides). In simple terms, if you draw squares on each side of a right triangle, the combined area of the two smaller squares will exactly match the area of the largest square. This relationship, known as the Pythagorean theorem, is fundamental in geometry and helps to understand the properties of right-angled triangles.
