According to the question,
Inverse is not consider as already proven statement. It is function which needs to calculate.
Hence, Inverse is not true.
Identity are formula which is not a geometric term.
Hence , identity is not true.
Theorem are geometric term, which can be used to prove other statements true as it is already proved.
Hence, corollary needs theorem to be proven true.
