When you are trying to decide if a line represents a line of symmetry you can think about folding the figure across that line. Once you make the fold, do all of the parts line up on top?

If yes, then the line represents a line of symmetry. 

If no, then the line does not represent a line of symmetry. 

This line represents a line of symmetry because if you fold on the black line, then one side would lay on top of the other and the parts would match up.

A quadrilateral is any two-dimensional shape with  $\displaystyle 4$ sides. The only shape listed that does not have $\displaystyle 4$ sides is a triangle. 

The only difference between a rectangle and a square is their side lengths. A square has to have $\displaystyle 4$ equal side lengths, but the opposite side lengths of a rectangle only have to be equal.
