If you are sitting in a room, the ceiling and the floor are parallel to each other. The walls are perpendicular to the floor and to the ceiling. So any line on these surfaces will be parallel to or perpendicular to any line on the other surface. And if they were not, the building could be quite unstable.
I think its true.....
What is an orthogonal line?
There wouldn't be train tracks, and you couldn't play tic-tac-toe.
-- 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 ?
A quadrilateral with one pair of parallel sides is called a trapezium (most of the world) or trapezoid (US) . If it was to have two pairs of parallel sides it would be a parallelogram.
No. Lines of longitude or meridians are not parallel.

Did you mean "real world examples of parallel lines"? If so, railroad tracks are a perfect example.
Because The lines of Longitude cross over each other at the top of the world which makes them not parallel. Parallel: Lines that never cross or meet And always stay the same distance apart.
"Parallels" or "Circles of Latitude".
Lines of Latitude run horizontally round the World and parallel to the Equator.
what is a perpindicular line?a street intersection.. u no?? like in traffic
Latitude = Fatitude = AROUND THE WORLD. It doesn't really mean parallel. The equator is a line of latitude. Latitude = Fatitude = AROUND THE WORLD. It doesn't really mean parallel. The equator is a line of latitude. Latitude = Fatitude = AROUND THE WORLD. It doesn't really mean parallel. The equator is a line of latitude. Latitude = Fatitude = AROUND THE WORLD. It doesn't really mean parallel. The equator is a line of latitude. Latitude = Fatitude = AROUND THE WORLD. It doesn't really mean parallel. The equator is a line of latitude. Latitude = Fatitude = AROUND THE WORLD. It doesn't really mean parallel. The equator is a line of latitude.
True
I think its true.....
As an example without them trains wouldn't be able to operate.
Transversal lines cut through or touch parallel lines as for example support sleepers on a rail track or transversal supports on a gate
