M KJR < m SRJ
M JKR > m RSJ
If KR is shorter than SJ it follows that the angle corresponding to that side is also smaller.
For example, angle corresponding to the side JR is m JKR.
Now imagine if the side JR were super long and also imagine if it were much shorter. The angle m JKR would be much larger when the side JR is super long.
