Religion is not something like a rightangled triangle.

Its lines, long and horizontal, broken only by lines that were vertical and by the lines of juts and recesses that were always rightangled, were as chaste as those of a monastery.

There were patios and pergolas in proportion, and all the walls, with their many rightangled juts and recessions, arose out of a bed of greenery and bloom.

With a flourish, Julius pulled out a sheet of paper: it was a map of the UK, over which someone had drawn a rightangled triangle.

The thing is, we were so caught up in the link between Stonehenge and the Great Pyramid, we never noticed the third corner of the triangle, the rightangled corner.

Alberto PérezGómez has discerned this metaphor in the writings of Fra Luca Pacioli, who "reminds us that Pythagoras's discovery of the proportions of the rightangled triangle is absolutely indispensable to build vertically and even to recognize justice, 'for without it, it is impossible to know the difference between good and evil, or to obtain any certain measure in our works.'"

We fed Spot her horsemeat in all manner of containers and bowls from the kitchen until we finally settled on a metal deepdish bread pan that was just the right size and that had really frustrating rightangled edges so the dog would spend hours trying to get at the bits in the corners.

Since we can construct squares like A and B for any shape or size of rightangled triangle, the theorem must be true in all cases.

If the square of two of them equals the square of the third then you can construct a rightangled triangle out of lengths of those sizes.

If, say, three Mona Lisas were drawn on a rightangled triangle, then the area of big Mona is equal to the area of the two smaller ones.
