What would be the right answer since im stupid

I say:
A tetrahedron is a pyramid with a *triangular* base

She says: A tetrahedron is a pyramid with a *triangle* base

and also (since im stupid again) would it be right if I said The coordinate plane is divided into four *quadrant*

cuz I think it would be better if I added an s

So the first one, you would be right. It's a triangular base.

The second one, you should say quadrants.

Hope this is helpful!

hooch has about 3% alcohol content so the 5 gallon 90% platinum vodka would be stronger because it has a higher alcohol content then hooch.  

ok if it wasn't the hans one it was probably c or he thought the mountain was collapsing on them.
