the two endpoints of a line make a line segment. endpoints are just endpoints
Two end points.
The distance between two points is called the "distance" or "Euclidean distance" in geometry.
If you know the end points then use the distance formula or simply use a ruler.
A line.
No, a line goes forever. A line segment has two end points
the line in geometry is a line segment that never ends
anode and cathode
The curve between two points is known as an arc. Arcs and circles are used extensively in geometry. They are used in the real world by engineers and digital artists.
Two dimensional geometry.
A line
In plane geometry, two points determines or defines one unique line.
In plane geometry, the shortest distance between two points is a line. In spherical geometry, the shortest distance between two points is a segment of a great circle. The distance between one point and another is known as the displacement.
