Question

Which of the following complete the proof above?

Answer 1

A

Explanation:

AC and CA represent the same segment, therefore have the same length and hence are congruent

Last step should be CPCTC because that's what is to be proven

Answer 2

(A)

Explanation:

To be honest, since all of them are different, as long as you get the first one right, you will get the others right. A is your answer, for the following reasons:

Reflexive Property: The Reflexive property states that the mirrored version of itself will always be congruent with itself. Generally, to make it easier, they will write it opposite (as they did in the given proof):

line AC ≅ line CA
