When would you use parallel lines in real life?

As a passenger on a train or when climbing a ladder.


When do you use parallel lines in everyday life?

parallel lines are everywhere. They are on the desk you are at, the windows, the very monitor you are looking at. Any two lines that run next to each other are parallel, and without this, very few things would be straight.


Examples for angles parallel lines perpendicular lines?

Real life example of parallel lines are railroad tracks and rows in a garden. Also the lines on a basketball court are parallel


Why do artists use parallel lines that do intersect?

I do not think lines can intersect if they are truly parallel.


Two parallel lines have equal slope?

Yes. You can use this to prove that two lines are parallel, in analytic geometry, i.e., geometry that uses coordinates.Yes.

How do recognize a set of parallel lines?

Parallel lines remain the same distance apart, always. Use a ruler to measure the distance at different intervals.Extend the lines out to see if they intersect.Check the line to see if there is the 'parallel' symbol.


How can you use the slopes and y-intercepts to determine if two lines are parallel?

If the lines are straight and have the same slope they are parallel, no matter what the y intercept is
