Parallel
Parallel lines will never intersect. They will stay an equal distance apart at all points.
If you can find the slope of both lines, then yes you can tell. The slope for parallel lines is the same - so if your slopes are the same, your lines are parallel. If you are measuring (less exact) the lines will be the same distance apart everywhere.

Two straight lines that remain equal distance apart are parallel lines.
Parallel lines are the same distance apart for all points along the line.

Two or more lines that are the same distance at all points are called parallel lines.
They are parallel lines
Contour maps have lines along points at the same height or elevation. The contours are usually drawn at regular intervals, such as every 10 or 50m of height change.Where contour lines are very close on a map, this shows that the height is changing a great deal over a short horizontal distance, and therefore the gradient is steep.Areas of shallow gradient will have contour lines that are a long way apart, showing that points that are a set distance apart in height are a large distance apart horizontally.
Parallel lines
perpendicular lines intersect each other at 90 degrees whereas parallel lines never intersect each other and remain equal distance apart from each other. Obviously the way to test if two lines are parallel is to measure their distance from each other at at least two points (the farther apart the better) to confirm that they remain equal distance apart, but to test if lines are perpendicular, with a compass with the point at the point where the two lines intersect, draw an arc (or three parts of an arc) that intersects one of the lines in two places and the other line in one place. If the distances between the lines at the points where they are intersected by the arc are equal, the lines are perpendicular.
They are parallel lines
Parallel lines.
That is the correct spelling of "parallel lines" (coplanar lines always a fixed distance apart).
Two straight lines that remain equal distance apart are parallel lines.
