Parallel lines are lines, which do not intersect with each other and can extend indefinitely in both directions. The distance between two parallel lines is always the same and the symbol for parallel lines is ‘II’. Some of the different properties of Parallel lines are:
- Straight lines are parallel to each other because the pair of corresponding angles are equal.
- If the alternate angles are equal, then the two straight lines are parallel to each other.
- The straight lines are parallel if the pair of interior angles are supplementary.
