How are parallel and perpendicular lines used in real life?

Hint: Parallel lines can be defined as the two lines which are in the same plane and are at equal distance from each other and they never intersect each other whereas the lines which intersect each other at ninety degree are known as the perpendicular lines. Here we will use the basic terminologies and accordingly will find out the examples in real life.

Complete step-by-step answer:
Using the terminology, we can say that we use the concept of parallel lines and the perpendicular lines in real life.
I.In real life, we use parallel lines –
A.Lanes of roads, i.e. Four-way lanes or the six-way lanes.
B.The two opposite sides of the blackboard and the whiteboard.
C.Opposite walls or doors in the room.
D.The tracks of rails.
E.The opposite sides or the edges of the cube.
F.Bookshelves.

II.Similarly, we use perpendicular lines in real life as –
A.The field of football or the volleyball
B.Object placed, such as television
C.The crossing of the railway track
D.Construction of the house where the floor and the walls are perpendicular to each other.
E.The bars placed with respect to wall
F.A straight tree perpendicular to ground.

Note: Know the concept of lines and apply accordingly. The parallel lines are denoted by the using the symbol $\parallel $ and if the two lines are perpendicular to each other then it is denoted by using the symbol $ \bot $ .
