Point
A point has no dimension. It is represented by a dot
Line
A line has one dimension. It is represented by a line with two arrowheads, but it extends without end. Through any two points, there is exactly one line. You can use any two points on a line to name it.
Plane
A plane has two dimensions. It is represented by a shape that looks like a floor or a wall, but it extends without an end. Through any three points not on the same line, there is exactly one plane. You can use three points that are not all on the same line to name a plane.
Collinear Points
Points that lie on the same line.
Coplanar Points
Points that lie in the same plane
Line Segment
A line segment is the portion of a line lying strictly between two points. It has a finite length and no width.
Endpoints
A single point indicating where a line segment or ray ends. A ray has one endpoint, and a line segment has two endpoints. exterior angle. An angle located outside two parallel lines or outside a closed figure. geometry.
Ray
A ray can be thought of as a half a line. It has a point on one end, and it extends infinitely in the other direction.
Opposite Rays
A ray in geometry is half of a line. A ray has one endpoint and extends indefinitely in one direction.
Intersection
In geometry, an intersection is a point, line, or curve common in two or more objects (such as lines, curves, planes, and surfaces). The most simple case in Euclidean geometry is the intersection points of two distinct lines, that is either one point or does not exist if lines are parallel.
