    I asked before, is statement 2 written correctly "m<4 = 110" That's what you have in your post. Did you copy it correctly?

    In the problem's given it states "m<2 = 110". I don't see that anywhere in the proof. That's why I say there's a step missing in this proof.

    You need to state m<2 = 110 before you can state m<4 = 110

    Let's say that before the first statement you wrote there is a line that states: Statements Reasons <2 is congr to <4; m<2 = 110 Given Then, write for reason b. Substitution

    b. can also be: Transitive property of equality. Either one is correct. Once again, for b. you have two choices, both being correct. You can write "Transitive property of equality", or "Substitution"
