I have a dumb question. I majored in engineering. I love math and I love geometry. I have taught a geometry class and tutored geometry. This is my question. Yesterday I was discussing different geometry books with a lady who tutors for alot of the private high schools in my area. We were discussing a certain curr. and I said they don't do proofs til the last chapter and she said no, it's from the very beginning and they do proofs all thru the book. I had a copy of the last chapter of the book from a student and I showed her the chapter that was titled "Formalizing Proofs"(the chapter was about 2 column proofs). Anyway she said oh no, the schools never get to that chapter, but proofs are throughout the bookfrom the very beginning(we were talking about Glencoe geometry). WEll, I dropped the subject and I don't want to appear as a dumb homeschool mom, so could someone explain what she's talking about. I thought the 2 column proof was "proofs". Is she just talking about when you have to prove SSS, etc. without writing it out. Thank you for your help.
