Parallelogram, or did you really mean trapezium?
The most common misalignment should produce that.

Can you misalign an enlarger and get a rhombus
from a square frame?

Well you mentioned "the parallel sides" in your post
so I went with that. Rhombus, trapezoid, from the
four sides of the negative I can't say how many
quadrilaterals might be formed.

I've an Issue of Camera and Darkroom wherein
an article describes a method of alignment which
makes use of the trapezoid as part of the
alignment procedure. Dan

Quick Check for Alignment

But you need an angle-measuring device to measure the
angles and see if they are the same.

A square or triangle, draftsman's or grade schooler's, is
needed. Ninety degrees is THE angle. Only TWO checks of
the internal angles need be made. If the object projected
is a rectangle and the projected image tests square at
two corners the enlarger is well aligned.

The same test will do to confirm progress when actually
working to align an enlarger. After all, the finale proof
of alignment is on the baseboard. Dan

That's true! And the OP should be more that happy to spend his $100 buying more film and paper IMHO.
