Intersecting and parallel lines. Intersecting lines are lines that cross each other.

Intersecting and parallel lines. Intersecting lines are lines that cross each other. Parallel lines are lines that never cross each other - they keep the same distance apart from each other - forever. Alternate angles Alternate angles form Z shape angles in the parallel lines.
