Perhaps he should stick to modelling

The bespectacled young maths teacher in this advertisement for the AQA exam board (on page 5 of this week's Times Educational Supplement) announces that he's "ready for the big changes in Maths". (Click on the picture to see a larger version.)

I hadn't realised just how big those changes are. On the whiteboard behind him he has labelled the longest side of a right-angled triangle as being the opposite, and one of the shorter sides as being the hypotenuse. These are no mere changes: they are revolutions.

Or perhaps he is not quite as ready as he thinks to be teaching mathematics. Perhaps he should stick to modelling.

Maybe the triangle is lying on its hypotenuse?

Or perhaps the third hidden side of the triangle isn't a vertically aligned one, in which case the labeling could be perfectly correct...

Its using sohcahtoa so the triangle must be right angled so there is no way the third hidden side can't be vertically aligned...

I'm late to the party, but the figure *could* look like this. (Not likely, of course.)

AQA cleverly trolls maths teachers with ambiguously-correct advert...

Sadly for them, the URL doesn't seem to work. Chop the "now" off the end and you get to the right page though.
