Can someone either explain to me what the question is asking or help me find the answer?

For each question, you have to try to prove that both triangles are congruent (exactly the same) by using the tests given. Since there is missing information in proving that the triangles are congruent, it's asking for the additional information required to prove that they are congruent while following the given test. Eg: for question 1, there needs to be additional information that two corresponding angles of each triangle are the same for the ASA test to work (currently we only know that the triangles share a common side).

I hope this has explained the question for you.
