Question

The adjacent edges of the door is a parallel line or a perpendicular lines

Answer 1

Step-by-step explanation:

(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 at some acute angle on each other.

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

Answer 2

Given,

The adjacent edges of the door are parallel lines or perpendicular lines.

Solution,

Know that parallel lines never intersect each other whereas perpendicular lines intersect each other at $\[90^\circ .\]$

Therefore, it is quite clear that the adjacent edges of the door are perpendicular lines.

Hence, the adjacent edges of the door are perpendicular lines.
