# Which of the following are models for perpendicular lines:

(a) The adjacent edges of a table top.

(b) The lines of a railway track.

(c) The line segments forming the letter ‘L’.

(d) The letter V.

**Solution:**

We will be using the concept of perpendicular lines to solve this.

The lines of a railway tracker and the letter V are not models for perpendicular lines.

The adjacent edges of a tabletop and the line segments forming a letter ‘L’ are models for perpendicular lines.
