Webline geometry: [noun] the geometry that assumes the line instead of the point as the element of space. In geometry, a line is an infinitely long object with no width, depth, or curvature. Thus, lines are one-dimensional objects, though they may exist embedded in two, three, or higher dimension spaces. The word line may also refer to a line segment in everyday life, which has two points to denote its ends (endpoints). A line … See more When geometry was first formalised by Euclid in the Elements, he defined a general line (now called a curve) to be "breadthless length" with a straight line being a line "which lies evenly with the points on itself". … See more In modern mathematics, given the multitude of geometries, the concept of a line is closely tied to the way the geometry is described. For instance, in analytic geometry, … See more Ray Given a line and any point A on it, we may consider A as decomposing this line into two parts. Each such part is called a ray and the point A is called its initial point.

A … WebApr 25, 2016 · In geometry, you draw a line with arrows at both ends. Arrows on either end of a line mean that the line goes on forever. A line segment is a piece of a line that has endpoints. A ray is a piece of a line that starts at a point and extends infinitely in one direction, kind of like a laser. It has one endpoint and one arrow.
