    instead of AD, you used AC because we know that they're equal

    whenever things like that happen, it's ok because of the "substitution" property

    the reflexive property goes like this A = B then B = A

    oops, sorry that's the symmetric property you see that the equation is symmetric, right ?

    the reflexive property is A = A you are equal to yourself it's like looking your "reflection" in your mirror

    if AD = AC, then AC = AD because of the? a. Reflexive property b. Symmetric property c. Transitive property d. Substitution property

    the transitive property says, A = B and B =C,,, then A = C think of it as B is the "translator" and lets A connect with C, so it's called the transitive property

    look at the eqn.s they look symmetric right? so it is the "symmetric" property

    Okay and what about this one AC = AC because of the? a. Reflexive property b. Symmetric property c. Transitive property d. Substitution property

    come on, this one is obvious :) look carefully at my notes, it explains it
