Nothing urgent just writing down some notes for geometry this year, I'm on online school and just want to be prepared. I wrote down area formulas and now I was wondering if you guys and gals could help me out and putting some geometry terms down below and writing their definition so I can have them in my notebook all year for future reference! E.g. Perimeter, the outside distance around a shape.
No term is to simple I need them all! Thanks guys!

You need just some definitions of terms that relate to geometry, and as many as possible. Is that correct?

yes please! @idku

bobobox · Answer

just so i can have them for safe keeping!

idku · Answer

Maybe you can say the term and I will define it, instead of having me list random things?
If not, then I will just do my best as you wish...

There is a shi(t)load of terms actually, so I don't even imagine the time in which I can go through all of them, I am sure you know most, so if you see some you don't know, I will help if I am here. For example this course outline here: https://alison.com/courses/Geometry/content if you see something you don't know, and don't understand even after you have read about it, please ask...

@idku are you still here? I think I understand the formula for an ellipsoid but was wondering if you could give me a problem so I can be sure I have it right?
