N, M and H
The letters A, K, M, N, R, V, W, Y, and Z all have lines in them that are not perpendicular.
The letter "L" in the alphabet has only one pair of perpendicular lines. It consists of a vertical line and a horizontal line that meet at a right angle, forming the distinctive shape of the letter. Other letters may have more lines or curves but do not feature just one pair of perpendicular lines.

There are letters in the alphabet with both parallel and perpendicular lines. In alphabetical order, they are E, F, and H. If the joining point can be considered perpendicular and parallel, then B, D, P, and R also match the criterion.
Many letters of the English alphabet have perpendicular lines. Perpendicular lines are like two lines making one corner of a square. So any letter that has two lines joined like the corner of a square has perpendicular lines.These letters have right angles: E, F, f, H, I, L T, t, and sometimes X, x.Keep in mind that the angles of the lines making the letters is effected by the font and whether or not the letter is italicized. For example, E is made of three perpendicular lines, but this 'E' has no perpendicular lines.
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.
