angle B is angle M
Look at the position.
Or the name of figures
(PMNO) and (ABCD) ,M and B are the second.
[tex]ABCD \rightarrow PMNO \Rightarrow \\ \angle{A} \cong \angle{P} \\ \angle{B} \cong \angle{M} \\ \angle{C} \cong \angle{N} \\ \angle{D} \cong \angle{O}[/tex]

Therefore, [tex]\angle{B} \cong \angle{M}[/tex]
