There's always one question each year that has students expressing their outrage via social media. "How dare they ask us something that might be difficult!", they scream in unison (between taking selfies and sexting).
Usually the world chuckles to itself, takes a look at the "impossible" question thinking, "I'm sure it can't be that hard, stupid kids", and then gets gradually more depressed as everyone realises they can't even begin to answer it.
And this year's "this'll make you wish you listened at school" brainteaser comes from a question given to Year 12 VCE students in Australia. Take a look below.
It looks quite intimidating, but it's actually (whisper it) not that difficult if you know a couple of geometric properties; namely the total number of degrees in a triangle, what an isoceles triangle is, and the total number of degrees in a circle. One student complained: "That exam wasn’t there to test us, it was to trick, no one could of (sic) prepared for that". As well as working on their English, we reckon they should have just listened more in Maths.
But can you do it? Pick your answer and then watch the video below to see it nicely explained.
