    [​IMG] Well, A1 is pretty easy... I just never paid much attention in Geometry. (I'm in Algebra 2 now.)

    Could someone please help me by answering these questions? I'd be most grateful...

    When is the Substition, and Division Prop. appropriate to use in a Proof?

    Substitution: you would use it if you needed to substitute an equal value with another value, say if angle c = angle b + 10, and c = 50, and there was an equation like a = b + 10, you can replace b + 10 with c, so a = 50.

    Division: when you need to divide? [​IMG] 3x = 9, you would divide by 3
