Answer 1

This is a very short proof. It requires 3 lines only. Two of which are already given by the teacher. The given statements are simply repeats of what the instructions provide.

The last line will be the statement
`m \angle ABC \cong m \angle GHI` and the reason is "transitive property". The last line of all proofs is what we're trying to prove.

The transitive property is where we have A = B and B = C, so it must mean A = C. Think of a set of dominoes where A leads to B then to C. In short, A must lead to C.

A similar idea is the substitution property. We replace one thing for another as long as the two things are equal.
