i got it quite quickly but its kinda hard to explain in a theory (atlest for me) but i can see where it came from. the orange shaoe is what makes the difference though. the height and the hole are changed by moving it. the green triangle and the orange shape take up most of the room the red did before. the shortening of the shape by moving the ornange leaves the required heigth that the red takes up now. i know that makes no sense but if you look at it and move it with your brain you get it .

it probably doesnt hurt that ive played about a bazillion hours of tetris in my life.

It just has to do with the fact that the two figures are triangles. Their hypontenuses don't take up exactly square areas, so when you rearrange them, you have to compensate differently depending on their relational position.

Seriously? I did the math, and each triangle had 180 degrees in it. But here's the weird part...

Since those two triangles have parallel bottom and right sides, by rule, their like angles should be identical. They're not. The upper-right angle on the large triangle is 69.444 degrees, while the same angle on the green one is 68.203 degrees.

Ohhhh.....

The big shape isn't really a triangle. Duh!

If you don't believe me, hold a ruler (or something with a straight edge) up to the screen. The shape bowes in the middle. It's not actually a straight line, so it's not a real triangle.

With a plasma screen I'd rather let you do all the math...
