I taught math to fifth and sixth graders. My mind has been warped ever since. The evidence follows in haiku:
Ninety degrees are
Also known as right angles
Angles most correct.
Obtuse angles are
Geometry’s friendliest
Shapes. Always open.
An acute angle
Isn’t necessarily
Attractive, my friend.
Perpendicular
Lines meet briefly at one point
Think intersection
Parallel lines seem
So lonely, these lines never
Touch, never will meet.
Geometry has
No irregularity
Like haiku, rules rule.
Quadrilateral:
Polygon having at least
Two lines parallel
