Looks like an answer from an LMH undergrad circa 1982.

My source is a friend of Mrs. C. She hated maths at school back then. We got talking about it (Euclid's book started flashing early 60s.....) and it just stuck. I gave her the reference to Polya's How To book. She understood it pretty well. She now loves the beauty of mathematics.
For the record, I performed the same idea on LI 5 respondents
1 geometric .. correct 1st time
4 trig boys .. all incorrect on the first attempt and did not check their results
For me, a flashback to 1965. I have that Euclid book somewhere..
