Poem For A Right Angle

The summer sun at noon shines bright And you are always everywhere Underneath and at immense height On the ground and in the air. Your birth place is unknown to me But your angle is always right A vertical perpendicular, carefree, To a horizontal line, firm and tight. Marked by an elegant small square, Your own cute symbol, neither acute Nor obtuse, ninety degrees of a stair, A skyscraper's desire to salute. A quarter-turn of a full circle, Three hours on an antique time piece, Go Angulus Rectus, ride your bicycle, The wheels rotate in patterned caprice. A model of democracy you are, Equal to all your peers in every tile, Euclid's fourth postulate, a classic memoir, But, oh, noble right angle, you never smile.
