First off, I have to say how disappointed I’m feeling about this Cycle365 group and it’s questionable arithmetic skills. I was sure that someone would point out that the feature photo of my latest post, A Pair of Pentagons, was actually a trapezoid, a four sided figure. I knew this of course – five is one of the easier numbers to count up to, if you have human hands – but posted it as a test. You all failed, and will have to skip recess for the next week to attend Integers 101.
Try to do better this time. The featured photo, from our ride to Elgin, includes both pentagons and hexagons. See if you can tell which is which! Also, extra credit if anyone knows the name for the spherical object itself.
