You've probably drawn all kinds of lines throughout your life. But, what is a line? A line is simply an object in geometry that is characterized as a straight, thin, one-dimensional, zero width object that extends on both sides to infinity. A straight line is essentially just a line with no curves. Most of the time, when we speak about lines, we are talking about straight lines! Here are some examples of straight lines.
Curved lines are what you get when you use the squiggle line in your computer Paint program. They are usually called a curve or arc and are not straight lines.
There are other kinds of straight lines that are helpful to learn.
Vertical straight lines go up and down. Horizontal straight lines go from left to right or vice versa. Parallel straight lines have the same slope and are the same distance apart, so they will never intersect. Perpendicular straight lines cross each other and form four perfect right angles in the process. Slanted or oblique straight lines are just as they sound: they are straight lines at an angle.
