一個代表畢達哥拉斯定理的圖形, 一個直角三角形, 用三個正方形的連接頂點在綠色的黑色板上形成 插畫檔

A grungy gradient blackboard with a diagram of a right angled isosceles triangle formed by three squares connected at the vertices. The diagram represents three squares denoting that sum of squares of two sides is equal to the square of the third side. Two squares in peach and orange color chalk lines form the the base and altitude or perpendicular and one side of slightly bigger yellow colored square placed tilted forms the hypotenuse. The geometric figure is hand drawn in peach, yellow and orange colored chalks. The lines of the sides are very neatly drawn. The squares are filled with scribble, scribbles or scribbling marks. The drawing is to the right in the frame and copyspace to the left. No people. The blackboard has a green gradient with dark corners and sides while the middle or center is in a lighter tone
