Question

3. which of the following statement is true about the triangles below
a) JKN=MKL by SSS
b) JKN=NKJ by AAS
c) JKN=KLM by ASA
d) JKN=LKM by SAS

Answer 1

The answer is D. JKN=LKM by SAS because:

JK is congruent to LK because there are 2 lines there that indicate that those are congruent. The same goes for NK and MK. The vertical angle theorem tells that the angles JKN and LKM are congruent. That means it's SAS on the diagram.
