M and O are congruent
N, M and O are similar
Your answer is: M and N are similar but not congruent
M and N are similar because the sides of M are proportional to sides of N:
[tex]\dfrac{2}{4}=\dfrac{1}{2}[/tex]
Two figures are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.
