Practice online or make a printable study sheet. It is often described as the shortest distance between any two points. 7 in An If you draw a line with a pencil, examination with a microscope would show that the pencil mark has a measurable width. A line is sometimes called a straight line or, more archaically, In geometry, a line can be defined as a straight one- dimensional figure that has no thickness and extends endlessly in both directions. is the set of point satisfying, The line through in the direction and Sorry, we could not process your request. Note that the line AB extends forever in both directions: When it has just one end it is called a "Ray". Show details, Parents, we need your age to give you an age-appropriate experience.

Join the initiative for modernizing math education. Euclid defined a line as a "breadthless length," and a straight line as a line that "lies evenly with the points on itself" (Kline 1956, Dunham 1990). https://mathworld.wolfram.com/Line.html.
