KL is parallel to MN, therefore the angles of triangles KJL and MJN are the same.
To find the similarity ratio, just divide the length of one of the sides of one triangle by the corresponding side in the other triangle. In this case, KJ is 2 and MJ is 4+2=6
So the answer is:
Yes because AA
KJL ~ MJL
2/6 or 1/3
