    Basic Geometric Terms

    • Point: Represents a precise location in space without any dimension.
    • Line: A straight collection of infinitely many points extending in two directions.
    • Plane: A flat two-dimensional surface that extends infinitely in width and length, but has no thickness.

    Relationships and Configurations

    • Collinear Points: A set of points that all lie on the same straight line.
    • Coplanar Points: Points that all reside on the same plane.

    Line Concepts

    • Line Segment: A part of a line defined by two endpoints and all points in between.
    • Congruent Segments: Line segments that share identical lengths.
    • Midpoint: A point on a segment that divides it into two equal lengths.

    Rays and Angles

    • Ray: A part of a line that starts at one point and extends infinitely in one direction.
    • Angle: Formed by two noncollinear rays sharing a common endpoint called the vertex.
    • Angle Bisector: A ray that divides an angle into two equal angles.

    Types of Lines and Their Intersections

    • Parallel Lines: Lines in the same plane that never intersect.

    Angle Relationships

    • Linear Pair of Angles: Two adjacent angles that sum to 180 degrees (supplementary).
    • Vertical Angles: Opposite angles formed by the intersection of two lines, usually appearing as an "X". They are congruent.
    • Congruent Angles: Angles that have identical measures.
    • Complementary Angles: Two angles whose measures sum to 90 degrees.
    • Supplementary Angles: Two angles whose measures sum to 180 degrees.

    • Equilateral Polygon: A polygon in which all sides are congruent.
    • Equiangular Polygon: A polygon with all angles equal.

    Special Segments in Polygons

    • Diagonal of Polygon: A segment connecting two nonadjacent vertices.

    • Circle: A set of all points equidistant from a central point (the radius).
    • Radius: Distance from the center of the circle to any point on the circle.
    • Diameter: A chord that passes through the center of the circle.
    • Congruent Circles: Circles with the same radius.
