Morphology

quadrilateral = lateral (semi-transparent) = quadri + lateral

'quadri-' is a technical combining form meaning 'four' that may be unfamiliar to average learners, so the composition is partly transparent.

Etymology

The word quadrilateral comes from the parts quadri- and -lateral, which mean 'four' and 'side'. So, when something is quadrilateral, it simply means it has four sides or is shaped like a four-sided figure.
