Name some parallel lines you can spot in your classroom.

Question

Homi · Accepted Answer

Parallel lines are lines that always stay the same distance apart and never meet.

Step 1 — Identifying Parallel Lines

Let us look around a classroom. We can find many straight lines. Many objects have pairs of parallel edges. We will list some common examples.

$\boxed{\text{1. Top and bottom edges of a blackboard}}$ $\boxed{\text{2. Left and right edges of a door}}$ $\boxed{\text{3. Opposite edges of a desk surface}}$ $\boxed{\text{4. Ruled lines on a notebook page}}$

Step 2 — Understanding Parallelism

We identified several pairs of lines. These lines are parallel. They maintain a constant distance from each other. They will never intersect, even if extended. This matches our definition of parallel lines.

Answer

(i) The top edge and bottom edge of the blackboard are parallel. (ii) The left edge and right edge of the classroom door are parallel. (iii) The opposite edges of a student's desk are parallel. (iv) The ruled lines on a notebook page are parallel.
