Got a bet going. What do you call this?
Having a debate about what you call a triangular ruler. Has one corner at 90 degrees and the other at 45 degrees. I say it is called a triangle (simple huh?) My friend says it is called a speed square. I know speed squares are used in carpentry. I see this used in drafting a lot but have never heard a technical name before. Thanks for helping to settle this bet.







It's called a 45 degree triangle. The 'other' kind is a 306090 degree triangle. Simple, huh??
Do you know what the other name for a (pair of) pliars is, you know the kind that has a slip joint? In the military, it's called a universal speed wrench (more trivia than you wanted to know). 





It's a setsquare over here

That's a set square.
