True; the area of the red square + the area of the green square = the area of the purple square
Explanation: This diagram represents the Pythagorean Theorem, where a^2 + b^2 = c^2, with the red square representing one of the square's sides (a), the green square representing the other side (b), and the purple square representing the hypotenuse (c). The areas of the red and green squares added together equal the area of the purple square, proving the theorem.
