  Missing square puzzle - Wikipedia, the free encyclopedia

In fact the red triangle is 8 squares across, and the angle of the hypotenuse is slightly shallower that that of the green triangle.
But because the lower 'triangle' has a 'hypotenuse' that is actually convex, this extra area is the equivalent of one square, which is why the lower shape has a missing square.
