two diagonal lines that aren't touching
An oblique prism looks slanted.
the gramatic sign of oblique how it look like
Check the link.
Since I can't attach illustrations here (can I?), I can describe one. If two congruent and parallel triangles have vertices joined by line segments, the line segments described will mark the boundaries of a solid.
They still look parallel but in the vertical plane.
Line segments that do not intersect are parallel lines

It will be parallel :D
------------- ------------- Or.
Segments of equal length are called congruent segments. You can identify them by congruency marks. congruency marks look like this on your line: ---l-----------l---
