I like the “value of the property” idea!

I did make the students with supposedly rectangular plots of land to still use the law of cosines to calculate the angles–the students never put them *exactly* in the shape of a rectangle, so it forced them to use numbers like 89 or 91 degrees. Often even the rectangular-looking ones weren’t, but perhaps that’s a function of nothing being rectangular around the area.

Thanks for reading!!
