Step 1: Understanding Parallel Lines.
Parallel lines are two straight lines that run in the same direction and are always equidistant from each other, meaning they never meet, no matter how far they are extended.
Step 2: Verifying the Options.
- Option (1): Two straight lines that do not intersect each other are parallel lines, making this the correct answer.
- Option (2): This describes intersecting lines, not parallel lines.
- Option (3): A zig
-zag line is not a straight line, and thus cannot be parallel.
- Option (4): A straight line is a basic geometric concept but is not necessarily parallel.
Conclusion:
Therefore, the correct answer is (1) Two straight lines do not intersect each other.
