In the diagram, figure PMNO is the image of figure ABCD.
In the diagram, figure PMNO is the image of figure ABCD.
angle B is angle M
Look at the position.
Or the name of figures
(PMNO) and (ABCD) ,M and B are the second.
\(ABCD \rightarrow PMNO \Rightarrow
\\ \angle{A} \cong \angle{P}
\\ \angle{B} \cong \angle{M}
\\ \angle{C} \cong \angle{N}
\\ \angle{D} \cong \angle{O}\)
Therefore, \(\angle{B} \cong \angle{M}\)
