-- Look around. You'll see a pair of them at every place on the floor
of your room where two edges of the floor meet.
-- At the same places, you'll also see a vertical line ... where two walls meet ...
that's perpendicular to both edges of the floor that meet there.
So, just in the room where you're sitting now, there are 12 pairs of perpendicular lines
at the 4 corners of the floor.
And another 12 pairs at the 4 corners of the ceiling.
Is that real enough for you ?

What are examples of horizontal lines in the real world?
Examples of horizontal lines in the real world include the horizon where the sky meets the land or sea, the straight line of a calm lake's surface, the boundary between the wall and floor in a room, and the straight line of a ruler placed flat on a table. Horizontal lines are parallel to the horizon and perpendicular to vertical lines.
What are some real life examples of linear pair angles?
The lines on a highway
Give some real examples for angles parallel lines perpendicular lines?
Some examples for parallel lines- railroad tracks, steps, buildings, paper, windows, ect. Some examples for perpendicular lines- stop sign, bridge, street intersection, driveway into a street, ect.
Give some real examples of vertical lines?
Vertical lines are lines that go straight up and down, with no horizontal component. Some real examples of vertical lines include the edges of a door frame, the corner of a bookshelf, and the sides of a skyscraper. These lines have a slope that is undefined, as they have no horizontal change.
What are real world examples of a midpoint?
Scales or balances.
