Answer:
p and n
Step-by-step explanation:
symmetry means they look like a reflection. cutting the letter X in half would give you two parts which look like > and <. Those two parts are reflections of each other. P is the only letter that can't be cut in half to produce two similar parts.
Hope this helps!
N and P
N and P grab a like and move the ends in a circle around each letter if they look symmetrical at any point that letter has a line of symmetry.
