{wiki=Proof_without_words}
"Proof without words" refers to a type of mathematical argument that conveys a proof or a mathematical result using visual reasoning or intuition rather than formal written explanations or symbolic manipulation. These proofs often employ diagrams, geometrical representations, or other visual aids to communicate a concept effectively. One common example is using geometric figures to show that the area of a shape is equal to another shape, such as demonstrating the Pythagorean theorem through a visual arrangement of squares on the sides of a right triangle.
