Question 1.
Which of the following are models for perpendicular lines:
Solution:
a) The adjacent angles of a table top
The adjacent edge of a table top are perpendicular to each other.
b) The line of a railway track
The lines of a railway track are parallel to each other.
c) The line segments forming the letter ‘L’
The line segments forming the letter ‘L’ are perpendicular to each other.
d) The letter V.
The sides of letter V are inclined at some a cute angle on each other
Hence (a) and (c) are the models for perpendicular lines.
