Quick math question

How many quadrilaterals can be formed on a 3 by 3 grid?

😱

42?

 

[chuckywang]

I think it's a bit more than that.

Edit: read over it. May not be right.
Edit2: not right. You ask how many can be formed on it. This is how many can be differnt ones can be formed on a 3 x 3 grid.

Can't you people do your own homework anymore? 🙂

I should have posted a less ambiguous question. The link you posted doesn't count symmetry. I'm trying to count symmetry. For example, look at that 1x1 square. It's only counted once in your link, but you can make 4 1x1 squares. I want to count all of them.

I think I got the answer now. Somebody else try to solve to problem so I can check with them. 🙂

are we assuming that verticies can only be on the intersections of the lines in the grid? if not, infinite

Vertices can only be points on the 3x3 grid.
