what is the most precise name for quadrilateral abcd with vertices a(-5, -1) b(-5, 3) c(-2, 3) d(-2, -1)

check the picture below.

hmmm is not a square, since is a 3x4, so all sides aren't equal.

is a quadrilateral, it has four sides alright.

though is not a square, it does have 4 right-angles at its corners... that means that is a rectangle, besides being a parallelogram.
