Answer:
The answer in the procedure
Step-by-step explanation:
we know that
If two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding interior angles are congruent
so
substitute the values
-----> is true
Therefore
JK is parallel to MN
Triangles OMN and OJK are similar by AA Similarity Postulate ( The three interior angles are congruent)
Because
m<OKJ=m<ONM ----> by corresponding angles
m<KJO=m<NMO -----> by corresponding angles
m<JOK=m<MON -----> is the same angle
