Let’s go through each number one by one and decide whether the lines are
parallel,
perpendicular, or
intersecting.
First, let’s remember what each word means:
-
Parallel = lines that never meet, always stay the same distance apart (like train tracks).
-
Perpendicular = lines that cross at a perfect right angle (like the corner of a square — 90 degrees).
-
Intersecting = lines that cross each other, but NOT at a right angle (they just meet somewhere).
Now, let’s look at each pair:
---
1. Two diagonal lines going in the same direction, never touching →
Parallel
2. Two vertical lines side by side, never meeting →
Parallel
3. Two lines crossing each other, but not at a right angle →
Intersecting
4. Two diagonal lines that are not parallel and will eventually meet if extended →
Intersecting
5. One vertical and one horizontal line crossing at a right angle →
Perpendicular
6. Two lines crossing, but not at a right angle →
Intersecting
7. Two diagonal lines, same direction, never meet →
Parallel
8. Two lines crossing, not at right angles →
Intersecting
9. Vertical and horizontal lines crossing at right angle →
Perpendicular
10. Horizontal and vertical lines meeting at right angle →
Perpendicular
11. Two horizontal lines, same direction, never meet →
Parallel
12. Vertical line meets horizontal line at right angle →
Perpendicular

Final Answer:
1. parallel
2. parallel
3. intersecting
4. intersecting
5. perpendicular
6. intersecting
7. parallel
8. intersecting
9. perpendicular
10. perpendicular
11. parallel
12. perpendicular
