Remember your geometry!

I remember when my dad sat in on my older sister’s 10^th grade geometry presentation during Parent/Teacher conferences back in the day.  The soon-to-be-retired teacher basically told the attending parents that geometry wasn’t all that important.

You just don’t say that parents, particularly one who is a Professional Engineer…

Dad must have been chewing on his slide rule to prevent himself from saying anything, until he got home that is.  I remember his frustration in that, at the very least, geometry teaches logical thinking and step-by-step problem solving. How is it that a math teacher missed the application of what he was teaching?
