What does a 100000 shape look like?

Answer 1

A 100,000-sided shape is called a myriagon. It would have 100,000 equal sides and 100,000 equal angles. Due to the large number of sides, a myriagon would appear nearly indistinguishable from a circle to the naked eye, as the difference in angles would be imperceptible at that scale.

Answer 2

You would need lots of patience to draw one of these, and an impossibly sharp pencil. Assuming that the question refers to a regular polygon with 100,000 sides it would look like a circle; even with a good microscope you would not be able to distinguish the vertices from a smooth curve.
