"Detail of a scene in the bowl of the letter 'P' with a woman with a set-square and dividers; using a compass to measure distances on a diagram. In her left hand she holds a square, an implement for testing or drawing right angles. She is watched by a group of students. In the Middle Ages, it is unusual to see women represented as teachers, in particular when the students appear to be monks. She may be the personification of Geometry. Illustration at the beginning of Euclid's Elementa, in the translation attributed to Adelard of Bath."

they say LOVE makes the world go round

only a square would disagree

love triangles are sometimes found

in life's complex geometry

all sorts of angles may abound

there's no obvious Q.E.D.

Obtuse Angles - like really stupidnewtonSmall.jpg (75895 bytes)

Right Angles - are there any wrong ones?

Complementary Angles - they go together well

Corresponding Angles - just penpals

A Cute Angle - how sweet!
