Key Geometry Concepts

Point: A geometric location with no size—no width, length, or depth—represented by a dot.
Line: A straight, one-dimensional figure extending infinitely in both directions; lacks thickness. A segment of a line that has endpoints is called a "Line Segment."
Plane: A flat, two-dimensional surface that extends infinitely; it represents the next dimension beyond points and lines.
Endpoint: The distinct points located at either end of a line segment, defining its extent.
Segment: A part of a line bounded by two endpoints, containing all points between them. Types include closed, open, and half-open segments.
Midpoint: The central point of a line segment, equidistant from both endpoints, effectively bisecting the segment.
Bisect: To divide something into two equal parts, applicable to line segments, angles, and shapes.
Ray: A line that begins at an endpoint and extends infinitely in one direction, analogous to sunlight.
Opposite Rays: Two rays that share the same endpoint but extend in opposite directions, exemplifying a dual path from a single origin.
Collinear Points: Three or more points that lie on the same straight line; any two points are always collinear.
Coplanar Points: Three or more points located on the same two-dimensional plane, often visualized as part of a flat surface.
Intersection: The point where two lines cross or meet, defined as the common point of intersection between them.
