circle yes a circle
A mobius loop which has one side and just one edge, could be your answer. Otherwise, a straight line segment may be it?
I guess you could say that a Mobius strip is a one-sided shape. Or a circle, because there are no corners or divisions where another side starts.
Irregular shape is the term given to an object which has 1 flat side, 1 curved side, no corners but has curved edges.
Points and corners are all vertices!
A circle has only one side and it is called its circumference.
hexagon
Well, honey, the shape you're looking for is a circle. It's got no angles and just one continuous side, like a sassy little diva twirling on the dance floor. So next time you're thinking about shapes, remember that circles are the OG smooth operators with no corners to cramp their style.
One curved side and NO corners.
There is not a shape with the most corners. You could always "one-up" the last shape. It is like with numbers, there is not a highest number, but instead there is infinity.
A sphere.
A cube is one
Oh, what a delightful name for a shape! A Polytagoreannippolopolislyginga would have many corners, my friend. Each side you add to a shape gives it a new corner, so the number of corners would depend on how many sides this special shape has. Just remember, every corner is a happy little place where angles meet and create beauty.
