\nAt its core, the Pythagorean theorem describes a universal truth about right-angled triangles. If ( a ) and ( b ) represent the lengths of the triangle’s two shorter sides (the legs), and ( c ) is the length of the longest side—that is, the hypotenuse, opposite the right angle—then the relationship ( c^2 = a^2 + b^2 ) holds true. This equation elegantly connects lengths in two-dimensional space.", "
