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.

To do:

We have to find which among the given are models for perpendicular lines.

 Solution:

(a) The adjacent edges of a table top are perpendicular to each other.

(b) The lines of a railway track are parallel to each other.

(c) The line segments forming the letter ‘L’ are perpendicular to each other.

(d) The sides of letter 'V' are inclined forming an acute angle.

Therefore, (a) and (c) are models for perpendicular lines.
