Thankyou for asking this. I have been searching this on the internet lately: i have been teaching grade 6 math. And i told them that david's star is a mathematically a curve. Because we can draw it without lifting the pencil. Then one child drew something that looked like confederate flag boundary and asked if it is also curve when drawn without lifting the pencil.
I actually confused them by drawing the 2d depiction of a closed cylinder and asking them if thats a curve. Sometimes it is interesting to discuss difficult unknown things in class. can someone plz tell me if these two figures are curves or not. The confederate flag and 2d drawing of a closed cylinder. And what book should i read to know better
