Where does the hole come from, what am I missing?
I didn't spend too much time thinking about this(about a minute) but anyone have a clue?

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.
