Study Notes

Essential Geometry Concepts

Point: A distinct location in space, lacking any dimensions such as length, width, or depth.
Line: Composed of infinite points, extends indefinitely in both directions, and has no thickness or width.
Plane: A flat surface extending infinitely in length and width, but lacking depth.
Line Segment: The portion of a line that lies between two specified points.

Geometric Relationships

Collinear Points: Points that lie on the same straight line or line segment.
Ray: A part of a line that begins at a specific point and extends infinitely in one direction.

Angles

Angle: Created by the intersection of two rays at a common endpoint; measured in degrees.
Vertex: The specific point where two rays converge to form an angle.

Types of Angles

Right Angle: An angle measuring exactly 90 degrees.
Straight Angle: An angle measuring exactly 180 degrees.
Acute Angle: An angle whose measure falls between 0 and 90 degrees.
Obtuse Angle: An angle measuring between 90 and 180 degrees.

Properties of Figures

Congruent Figures: Figures that possess identical size and shape; corresponding sides and angles are equal.
Line Bisector: A line segment or ray that divides another line segment into two equal parts.
Angle Bisector: A ray or line that divides an angle into two equal angles.

Angle Relationships

Adjacent Angles: Two angles that share a common side and vertex, with no overlapping interior points.
Linear Pair: A set of two adjacent angles formed by the intersection of two lines, which sum up to 180 degrees.
Vertical Angles: Angles located across from one another when two lines intersect; they are non-adjacent and have equal measures.
