Done. Much thanks (as noted in the post, just above my bio). That's a perfect example, with the two stems translating directly into English.

(Since I tried to limit all examples to one line in length, I did not add the "straight lines" phrase. But that's hinted in the term "quadrilateral." Godda love the magic of language!!!)

Again, much appreciation for helping me to "add value."

And extra, additional, bonus thanks to the current value of Steem!!!! Apparently, on Steemit, "adding value" is reciprocal.
