       Is this geometry problem fun or is it evil? “prove LMNO is a parallelogram” #matheducation

       @futurebird I get that the cross-marks are equal lengths, but what do the arrows mean? Parallel lines?

       @futurebird I think it's fun but I'm long enough out of geometry that I'm not sure my memory for the rules for similar triangles is totally solid.

       @futurebird yesSomehow my trig education from millennia ago didn't even use <, << as parallel so I had to look that up but I'm sure it's well established in your context.

       @futurebird It's evil, but not for the reason you think. The problem reminds me that I liked geometry and was good at it, but that was half a century ago and I might be getting old.

       @futurebird It is at least twice as convoluted as the hardest problem of the kind I ever had to solve, back in the day

       @futurebird enough of both that i might swap the labels around such that it’s the LMAO parallelogram 😹

       @futurebird Prove to my satisfaction or someone else's?

       @futurebird @llewelly Looks like something I would have enjoyed when my geometry wasn't as rusty.

       @futurebird Is this related to Wittenbauer's parallelogram in some sneaky way?https://archimedes-lab.org/2025/05/29/wittenbauers-parallelogram/

       @catselbow Yes, sort of, having a look at it. (I had not seen Wittenbauer's parallelogram before, but this is perfect for these lessons...) Wittenbauer's parallelogram works by making triangles and connecting their midpoints. This makes sets of parallel lines.Something similar is going on above.

       @futurebird Depending on the rigor you're expecting not bad to annoying.
