If there's something that especially pleases me,

It's when the two lines of a triangle make 90 degrees.

Less than that might be called "acute",

But it's the perfect 90 that's really a beaut!

For obtuse angles, I don't have the time,

They're at their worst when they're almost a straight line!

God proves her existence by leaving us clues,

And there's no clue clearer than the hypotenuse.

I hope you'll forgive me if I come across as rude,

But the beauty of right-angles is rarely understood,

Only Pythagorus and I have been left with our mouths agape,

At this truly and wonderfully perfect shape!
