Answer :

Perpendicular means the lines form a 90 degree angle or right angle where they meet so letters that have perpendicular lines could be:Uppercase "T"Uppercase "L"Uppercase "F"Uppercase "E"Uppercase "X" and lowercase "x" are close but I don't think they make a right angle.You could argue that "B", "D" and lowercase "t" also have perpendicular lines but they are not straight lines so I don't know if those count.

Description : What letters have no parallel perpendicular or intersecting line segments?

Last Answer : The answer depends on the font being used. In a serif font a lot more characters will have intersecting lines. So the answer is likely to be a subset of the upper case sans serif letters C, I , J, O, S. But even here, the letter O does have parallel segments, and possibly C as well.
