Grr I hate it when they do that. Another question had shown a right triangle (but not stated it was) and then said each of the bases is 1... so immediately I said, oh, well the hypot then is the sqrt(2)... but D was the answer again. Stupid. Why try trick people? That doesn't measure intelligence.

Ok, so lets assume that these lines do not meet in center. If this is the case, then how can opposite regions be equal? Unless you can't even assume that those are straight lines... bizarre.
