Answer:
1. Given
2. Similar Lines(given in diagram)
3. Vertical Angles
4. SAS(or Side-Angle-Side)
Step-by-step explanation:
1 is given because that is whats given to you.
2 is Similar Lines because, on the diagram, when a line has a small dash on it and another line has the same dash, this means that they are similar.
3 is Vertical Angle because a vertical angle is an angle that is reflective of another angle and, according to the Vertical Angle Theory, all vertical angles are equal.
4 is SAS because you always go counterclockwise on the triangle when finding the congruent abbreviation and her you can see it is Side(LN=NW), Angle(LNS=WNK), Side(SN=NK).
