For easier use, mathematicians usually use the number of sides and add -gon to the end of it. In other words, a 175-sided figure would be called a 175-gon for casual use.When using traditional Greek terminology (such as hexagonfor a six-sided figure), a 175-sided figure would be called a hectakaiheptacontapentagon.
It's quite acceptable to call it a 43-agon but what's more important is knowing how to work out its properties.
A one sided shape
Any of these shapes is practically circular. A 20-sided shape is an icosagon. a 50-sided shape is a pentacontagon (aka pentecontagon). A 100-sided shape is a hectogon (aka hecatontagon). A 1000-sided shape is a chiliagon.

Septagon
I guess its either a regular pentagon or a irregular one. Not sure if there anything else to it =P
Oh, dude, a 43 sided shape is called a tetracontatrigon. Yeah, I know, it sounds like something out of a sci-fi movie, but that's the technical term for it. So, next time you're doodling and accidentally draw a 43 sided shape, you can impress your friends with your newfound knowledge.

The name for a 57 sided shape is derived by combining the name for a 50 sided shape with the name for a 7 sided shape. A 57 sided shape is called a pentacontaheptagon.
