thats partially correct. it wouldnt make sense if one was a triangle, and the other not - both arent triangles. if they were to be triangles, the two smaller triangles (red and green) would have to be proportional in length (for the angles to align, to maintain a straight line for the hypotenuse of the larger triangle). this isnt the case here, as the red triangle is 3/2s the height of the green triangle, but is .5 units larger than 3/2s the base of the green.
