Answer: [tex]\angle{B}[/tex]
Step-by-step explanation:
Given: Triangle ABC congruent triangle MNO.
We know that if two triangles are congruent then their corresponding angles and sides are also congruent by CPCTC [Congruent parts congruent triangle]
If triangle ABC congruent triangle MNO, then
[tex]\angle{A}[/tex] corresponds to [tex]\angle{M}[/tex] [First letters]
[tex]\angle{B}[/tex] corresponds to [tex]\angle{N}[/tex] [Second letters]
[tex]\angle{C}[/tex] corresponds to [tex]\angle{O}[/tex] [Third letters]
Hence, the corresponding angle congruent to [tex]\angle{N}[/tex]=[tex]\angle{B}[/tex]
