1.	Which of the following are models for perpendicular lines:(a) The adjacent angles of a table top(b) The line of a railway track(c) The line segments forming the letter ‘L’(d) The letter V.
Answer» (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.

Which of the following are models for perpendicular lines:(a) The adjacent angles of a table top(b) The line of a railway track(c) The line segments forming the letter ‘L’(d) The letter V.

Answer»

(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.

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.
