Every once in a while, a maths puzzle, brain teaser or exam question aimed at a small child will come along and expose huge gaps in our knowledge.
Said problem/puzzle/ question will basically reveal that many of us have forgotten the vast majority of what we learnt at school.
It’s to be expected.
School was a long time ago for many of us. And if maths wasn’t your forte, then it’s natural to not retain many of its finer points.
The ‘how many triangles’ puzzle which has recently surfaced is a case in point.
It was shared by journalist Jitesh Pillai and took no time to baffle the masses.
At first it’s easy to keep track of the triangles.
There’s one big one. One at the top made of three smaller triangles – that’s five triangles so far.
The it starts to get a little more complex. Stare at this too long, and you’ll start to see triangles – and potential triangles – everywhere.
The word triangle will eventually lose all meaning for you.
