Pagkilala ng Parallel lines, Perpendicular lines at Intersecting ... - Free Printable

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
