The shapes are exactly alike, however when you place them differently, they take a different a higher/lower percentage of the graph. The red triangle has a slightly different angle thus taking more space when place on the top of the pic.
I just copied the outline of one of the bottom pic over the top pic, you can see the difference. I'm not sure why 'cube wise' it's so apparent. However you can see the difference in the outline.
Keeping my fingers crossed, never put an image up.
