E,f,h,i,n
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 look like two straight lines that meet or intersect at a 90-degree angle. The capital letter T is an example of what they might look like.
Yea
Perpendicular lines meet at right angles and in the alphabet in capital letters they are E T F H and L
It is the capital letter N that has vertical parallel lines.
0 because the letter t does not have anything to be parallel with but it is intersecting.
X and T
None but it does have perpendicular lines
Railroad tracks or the number 11 are parallel lines. A cross or a small t are perpendicular lines. Also the two ll's in the middle of parallel are parallel lines.
No European capital city begins with the letter T.
None and no diagonals
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.
No shape starting with the letter t has 2 and only 2 pairs of parallel lines. Under special circumstances a trapezoid could have both sides parallel, but this is often not the case. This special case only exists in theory but is very rare. If we start talking about 3 dimensional shapes versus 2 dimentional shapes, we can have another answer but that is a different situation.
A letter
I think it is these: Parallel: Perpendicular: it looks like an upside down capital "T"
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.
