Capital letters that have parallel lines include "H," "I," and "E." These letters have horizontal lines that are parallel to each other. The letter "H" has two parallel horizontal lines, the letter "I" has one, and the letter "E" has three parallel lines.

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.

How about Z, E or F
The letter z is one which has no lines of symmetry so the answer is 0.

When two parallel lines are intersected by a transverse line, they form eight angles. You can consider the parallel lines as the horizontal lines of the letter Z and the transversal as the sloped line of Z. Then the two angles in that Z-shape are the Z angles. The transversal for Z-angles can slope either way. It can be proved that Z-angles, properly called ALTERNATE angles, are equal.
There are no perpendicular lines in the letter Z
Capital letters that have parallel lines include "H," "I," and "E." These letters have horizontal lines that are parallel to each other. The letter "H" has two parallel horizontal lines, the letter "I" has one, and the letter "E" has three parallel lines.
No.
No
A zero slope is horizontal or flat, and an undefined slope is vertical or straight up and down. While this answer is in the textbook and notebook of anyone studying the subject, it is easy to get the two mixed up on test day. Try the following mnemonic (memory aid): Look at the letters "z" for zero, and "u" for undefined. The top and bottom of the letter Z are horizontal lines. The two sides of the letter U are vertical lines.
Any two lines that meet must be in a plane. The plane may not necessarily be horizontal or vertical such as X-Y or X-Z or Y-Z
