I can draw a regular pentagon around a clock face at 12 minute intervals. That's fun!
I know the mathematics works for a regular pentagon, yet I have looked at Euclidean and other pentagons and followed instructions.
We assume a regular pentagon can be drawn on a circle with straight edge and compass yet I can't and ALL the examples of published regular pentagons drawn by compass and straight edge on a circle have been wonky.
And yes, I'm looking at Eu kid!
So my request is, get out your geometry books and turn to the image of the pentagon hand-drawn with compass and straight edge on a circle.
Measure the side lengths. Are they all consistent to 1 mm?
Some I've seen are out by 1 cm yet said to be regular.
