The letter's "H", "I", "E", and "F".
They are: E T F H and L
Parallel: E, F, H, I, M, N, O (in some fonts), U, Z. Perpendicular: E, F, G, H, L, T. Many more letters have perpendicular lines in serif fonts. Also, there are letters, such as D, in which the ends of the curved section are parallel to one another and are perpendicular to the vertical element.
Perpendicular lines meet at right angles and in the alphabet in capital letters they are E T F H and L

They are: E T F H and L
The letter - H
There are no perpendicular lines in the letter Z
yes it is perpendicular
Yes the letter H does have two lines of symmetry. First you can bisect the letter "H" with a vertical line placed though the centre of the H. It can be cut laterally and Bilaterally. Secondly, you can cut an H evenly by drawing a horizontal line though the points of parallelism on each perpendicular transversal.

the letter A, the letter V, the letter X is the best example. If by perpendicular you mean 90º, the answer is E, F, I, L, and T. A, V and X are not perpendicular, they are acute angles.
The answer to this probably depends on (a) the font and (b) wheter the uppercase letter or the lowercase letters are considered. In this particular font, in uppercase B D E F H I K L M N P R and T all have perpendicular segments, G has a short perpendicular segment J has a perpendicular segment which ends in a curve U has two perpendicular segments joined by a curve and in lowercase b d h i k l m n p r and u all have perpendicular segments a f g j and t all have perpendicular segments with curved parts.
