God knows....We've got this on the wall of our toilet.......I've often had a p!ss lasting 15 minutes or so....Still never managed to wotk it out. Thought it might have something to to with the angles of each diagram....but that just sounds like a load of old bo!!ox really!!!

Work it out mathematically, it's really quite obvious.

Try pythagoras' theorem on the parts and whole and remember about similar triangles and their angles, etc. In fact, you can even use trig to mathematically 'solve' it.


Or you can just notice that it's not actually a triangle

Neither hypotenuse is actually straight.

Easy, the green and red triangles don't have the same angles!

The red one has a gradient of 3 in 8 : it goes up 3 squares for every 8 along. Gradient = 0.375

The green one 2 in 5 : it goes up 2 squares for every 5 along. Gradient = 0.4

So it's just an optical illusion, the overall shape is not a triangle
