Crosswalks are typically marked with white painted lines. However, not all pedestrian crosswalks are painted. It's best to use judgement when slowing down at intersections or yielding as to what would constitute the crosswalk.

Intersecting lines are two lines that cross in a coordinate plane. So, yes, intersecting lines cross.
Either intersecting lines or perpendicular lines
Perpendicular lines are lines that cross at right angles. Intersecting lines can cross at any angle.
Two lines cross or intersect at a point.
Straight lines that never cross are called parallel lines.
Skew lines can refer to non-coplanar lines and, if that is the case, they cannot cross.
Parallel lines never intersect/cross.
Magnetic field lines don't cross.
Diverging lines are not parallel and never cross.
