Perhaps "skew" is what you're looking for.
parallel
Perpendicular
perpendicular
A right angle is an angle that measures exactly 90 degrees on the protractor, wheres perpendicular is simply a word which means 2 lines that meet at one end, the opposite of parallel, which means 2 or more lines that don't meet at the end.
Parallel means a line of latitude. ----
I am not sure about the specifics of the test, but the word perpendicular means "at 90 degrees to"
Perpendicular means 'at right angles to'.
In the absence of a definition, I'll provide one. What is a 13 letter word for vertical? Answer: perpendicular
you need to finish the question.. if two line are what? perpendicular ? Parallel?
Horizontal.
The word parallel is an adjective. It means to be equally distant at all points.
Perpendicular is straight up and down, having a sharp pitch or slope. It is a style of English Gothic Architecture. So the term would refer to the 'walls' rather than the roof. Parallel in Geometry are straight lines in the same plane, but never meeting. Building may be parallel to each other. Neither word applies
