is Intersecting slanted?
- Intersecting lines are lines that meet at a single point, called the point of intersection. Learn the definition of lines, line segments, intersecting lines, and parallel lines, with examples of each.
Lines & Line Segments
- We know that, generally speaking, a line is a straight, 1-dimensional figure between two points. In geometry, though, there is a distinction between line segments and lines. A line segment is what you probably think of when you think of a line. It's straight and stretches between two endpoints:
a line with two endpoints
- A line, however, is different from a line segment because it extends infinitely in both directions. It has no endpoints. Of course, we can't draw an infinite line, so we signify a line by placing arrowheads on both ends:
line with arrowheads at either end
- We can name lines using two points they extend through. For example, we would call this line AB:
- We can name lines using two points they extend through. For example, we would call this line AB:line including points a and b
