Those are parralel lines.
No.
Perpendicular lines have slopes that the inverse of each other. If one line has a slope of 1/3, the other has a slop of 3/1
Well its not slop, but slope and its adjective form is sloppy.
Trapezoid
Yes.
it has 4 parallel lines
2
parralel lines
A triangle cannot have parallel lines.
2
Yes.
there are no parralel line in a rhombus
Any two lines, if their slops are equal, are either parallel or else the same line.
Yes, all vertical lines are parallel, for a given coordinate system.
If two lines have the same gradient, then this means they are travelling in the same direction. Lines travelling in the same direction will never touch or cross each other even if extended to infinity. Lines with such a property are called "parallel lines." This is assuming they are not just exactly the same line.
2 parralel lines are lines that are parallel to each other so they are oppoosite to eathother x
