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 letter's "H", "I", "E", and "F".
No
Perhaps "skew" is what you're looking for.
yes
E
z
No because there is no other line parallel to I
It is the capital letter N that has vertical parallel lines.
They are: E T F H and L
The letters in the alphabet that contain parallel lines are "H," "I," "K," "N," "X," and "Z." These letters have two or more straight lines that run alongside each other without intersecting. The letter "T" also contains perpendicular lines, as it has one vertical line intersected by a horizontal line at a right angle.
0 because the letter t does not have anything to be parallel with but it is intersecting.
