Answer:
Can you show me the fourth choice? I will be able to answer once you post it. If this is a four choice problem, then it is the choice that I can not see.

Answer:
Vertical angles
Step-by-step explanation:
The diagram shows two straight line intersecting to form vertical angles. One of such pair of vertical angles formed is <1 and <2.
Vertical angles are congruent to each other. Therefore, the reason why <1 ≅ <2 is because they are vertical angles or vertical angles pair.
It might seem silly, but it's important to say that something is equal to itself. This applies to numbers like saying 2 = 2 and it also applies to geometric lengths as well. In line 5, we say that segment DB is the same length as segment DB. In short, DB is congruent to itself. This property is known as the reflexive property of congruence. You can think of a mirror giving off a reflection which has a similar word structure to reflexive.
You are correct if you were going to select choice B as the answer.
Since all reflections are inverse of itself, carrying any reflection about the same axis twice will carry the preimage back to itself.
