Just look at it! Look how they've placed the parts, compare the two triangles. See that it works. They have placed the parts differentlly and got a hole. It's really that simple. I fail to se what's so strange about it. Explain please (wrote plz first <img src="/ubbthreads/images/graemlins/shame.gif" alt="" />).

It's strange because there's a triangle that's 13 long and 5 high. When they rearrange it, it is still 13 long and 5 high, but it somehow takes up more area than before.
<span class='standouttext'>Spoiler : </span><span class='spoiler'>The original and final shapes aren't triangles. There is a slight angle where the two triangle pieces meet.</span>
