You can put this solution on YOUR website! What is the precise name of a quadrilateral with vertices (-1,2), (3,4), (5,0), (1,-2)?
-----
Label the vertices:
A(-1,2), B(3,4), C(5,0), D(1,-2)
----
Find the lengths of the sides.
If they're the same length, it's a parallelogram.
Find the slope of AB and BC.
If AB is perpendicular to BC, and the lengths are equal, it's a square.
Start with that.
