Pythagorean theorem with squares — free printable diagram

About this illustration

This flat illustration visually explains Pythagoras' Theorem, showing a right-angled triangle with squares constructed on each of its three sides. The two smaller squares, colored blue and orange-red, are labelled with their areas '9' and '16' respectively, corresponding to sides 'a' and 'b'. The largest yellow square, built on the hypotenuse 'c', is labelled with its area '25'. Below the geometric representation, the theorem is explicitly stated as the equation "a² + b² = c²". This diagram is ideal for teaching geometry and algebraic relationships in mathematics classrooms, suitable for slides or as a reference image on worksheets for US, UK, or international curricula.
