How can this be!?!

What do you think???

The partitions are the same, but the overall size of the triangles are not the same.

This should probably go in the math & science forum.

You know, I’ve seen this thing before, I don’t see what exactaly is supposed to be intriguing/confusing/puzzling about it… I can see why the second triangle has a blank space…

The slope of the red and green triangles are not the same (2/5 != 3/8). Therefore the top composite triangle’s hypotenuse is actually slightly concave, while the bottom composite triangle’s hypotenuse is slightly convex, which means that the bottom composite triangle has a larger area (hence the gap).

Very Cool Explanation!

excellent explanation, I put one triangle over the other in this .gif, by changing the opacity, one can clearly see the difference in the slope of the triangles
