What capital letter appears to have parallel lines?

The letter H has a pair of parallel lines

Well the definition of parallel is two lines side by side that can stay traveling in a continuous line keeping the same space between one another.

With this we can conclude some upper case letters that have parallel lines.

E
The 3 lines in E can travel horizontally side by side forever keeping the same distance 

F
The 2 lines in F can travel forever side by side keeping the same distance as well.

H
This is the best example where the two lines on either side of H can travel vertically forever and keep the same distance

M and N
Both of these contains lines on either side of them which can travel vertically forever and always stay side by side.

Z 
Z is the last example of this in the English alphabet as the top and bottom of Z can travel horizontally forever and remain side by side.

Hope this helps!
