That's about all the trapezoid related words we've got! I hope this list of trapezoid terms was useful to you in some way or another. The words down here at the bottom of the list will be in some way associated with trapezoid, but perhaps tenuously (if you've currenly got it sorted by relevance, that is). If you have any feedback for the site, please post it here, but please note this is only a hobby project, so I may not be able to make regular updates to the site. Have a nice day! 🐜
