Quick question, is crescent a type of rotational symmetry?

It's also a reflectional symmetry right?

it's not rotational symmetry because when you rotate it by any angle (except 360° or a multiple thereof), it looks different

Yeah, i think this crescent being rotational is an inside meme

yes it has a pi type plan passing through the vertical middle (vertical middle of the whole picture)
also a C2 axis rotating along the same line

it actually has a 180° rotational symmetry axis

Then it's reflectional symmetry, not rotational. This "Crescent rotational" is an inside joke, just like "Blinker Fluids"

He means rotating in 3D space.

Doesn't make sense, it will still turn out different

How do you differentiate between the two sides?
