Answer:
B
Step-by-step explanation:
To solve this, we just need to keep in mind the following:
Vertical angles are always congruent.
Vertical angles are formed by a pair of intersecting lines. The angles across from each other are what we call vertical angles.
So, to find the congruent pair of angles, we just need to find a pair of vertical angles.
In the options given, the only option with a pair of vertical angles would be <13 and <15.
There are a few options that would be congruent if the line segments were parallel, but that is not a given.
