    Study Notes

    Angle Types and Properties

    • Acute angle: Measures greater than 0° and less than 90°.
    • Obtuse angle: Measures greater than 90° and less than 180°.
    • Right angle: Exactly 90°.
    • Straight angle: Exactly 180°.
    • Supplementary angles: Two angles whose measures add up to 180°.

    Angle Relationships

    • Adjacent angles: Share a common vertex and side, but have no common interior points.
    • Linear pair: A pair of adjacent angles that form a straight line.
    • Vertical angles: Non-adjacent angles that are formed when two lines intersect.

    Line and Segment Definitions

    • Angle: Formed by two rays with a common endpoint (the vertex).
    • Line: A straight figure that extends infinitely in both directions.
    • Line segment: A part of a line that is bounded by two endpoints.
    • Ray: A portion of a line that starts at a single endpoint and extends infinitely in one direction.

    Points and Planes

    • Point: A location with no size or shape; a fundamental concept in geometry.
    • Line: Extends infinitely, comprised of points in a single dimension.
    • Plane: A flat surface made up of points extending in two dimensions.

    Collinearity and Coplanarity

    • Collinear points: Points that lie on the same straight line.
    • Coplanar figures: Shapes or points that are contained within the same plane.

    Polygon Properties

    • Polygon: Closed, two-dimensional figure with straight line segments.
    • Equiangular polygon: A polygon with all angles congruent.
    • Equilateral polygon: A polygon with all sides congruent.

    Bisectors

    • Angle bisector: A ray that divides an angle into two equal parts.
    • Segment bisector: A figure that divides a line segment into two equal halves.

    Additional Concepts

    • Intersection: The set of points that two figures have in common.
    • Space: A three-dimensional set encompassing all points.
    • Polyhedron: A solid figure composed of polygonal faces.
    • Midpoint: The point that lies exactly halfway along a line segment.

    Undefined Terms

    • Undefined terms: Concepts that cannot be formally defined but can be understood through examples, such as point, line, and plane.
