caption: The image shows a black and white drawing of a triangle with alphabets and numbers written on it, which is believed to be a representation of the Pythagorean theorem. The triangle is composed of a series of interlocking triangles, each with its own set of numbers and letters, arranged in a symmetrical pattern. The numbers range from 0 to 9, and the letters are written in a bold font. The background of the image is a plain white, allowing the triangle to stand out and be the focus of the drawing.
