What is a Line? In geometry, a line is a straight one-dimensional figure that does not have a thickness, and it extends endlessly in both directions. Diagram A represents a line. It does not have any endpoint. The two arrows at each end signify that the line extends endlessly and is unending in both directions.
Line. more ... In common language it is a long thin mark made by a pen, pencil, etc. In Geometry a line: • is straight (no bends), • has no thickness, • and extends in both directions without end (infinitely). One end makes it a "Ray", and two ends makes it a "Line Segment". Try moving points A and B:
Lines. A line is a one-dimensional figure, which has length but no width. A line is made of a set of points which is extended in opposite directions infinitely. It is determined by two points in a two-dimensional plane. The two points which lie on the same line are said to be collinear points.

- What are the types of lines?In geometry there are four types of lines: Horizontal Line Vertical lines Parallel lines Perpendicular lines
- What is a vertical line?A vertical line is a line drawn from the bottom to the top in a straight direction.
- What is a horizontal line?A horizontal line is a line drawn from left to right in a straight direction.
- What is a line segment?A line segment is a part of line which has two fixed endpoints.
In geometry, a straight line, usually abbreviated line, is an infinitely long object with no width, depth, or curvature, an idealization of such physical objects as a straightedge, a taut string, or a ray of light. Lines are spaces of dimension one, which may be embedded in spaces of dimension two, three, or higher.

3 days ago · A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions. A line is sometimes called a straight line or, more archaically, a right line (Casey 1893), to emphasize that it has no "wiggles" anywhere along its length.
