Study Notes
Geometry Key Concepts
- Equidistant: Describes points that are equally distant from a common point.
- Circle of Points: A circle drawn around an object with a radius of 2 cm has infinitely many points on its circumference.
- Point: A fundamental concept in geometry representing a precise location with no physical dimensions (length, width, height).
- Line: A straight one-dimensional figure that extends infinitely in both directions, has length but no width or height, and consists of at least two points.
- Plane: A flat two-dimensional surface that extends infinitely, characterized by having length and width but no height and containing at least three non-collinear points.
- Space: The three-dimensional construct that contains all points, defined as a set of at least four points that are not all within one plane.
- Collinear Points: Points that all lie on the same straight line.
- Coplanar Points: Points that lie within the same plane.
- Intersect: The action of two figures meeting or cutting each other.
- Intersection of Figures: The collection of points shared by two or more figures.
- Dashes in Diagrams: Indicate parts of figures that are obscured from view.
- Vertical Planes: Represented by figures with both sides extending vertically.
- Horizontal Plane: Represented by figures where both sides extend horizontally with no vertical sides.
- Segment: A defined portion of a line bounded by two distinct endpoints.
- Ray: A part of a line that begins at one endpoint and extends infinitely in one direction.
- Congruent Segments: Line segments that have identical lengths.
- Midpoint of a Segment: The point that equally divides a line segment into two congruent segments.
- Bisector of a Segment: A line, ray, or plane that meets a segment at its midpoint, thus dividing it into two equal parts.
- Angle: Formed by the union of two rays that share a common endpoint, known as the vertex.
- Acute Angle: An angle measuring greater than 0 degrees and less than 90 degrees.
- Right Angle: An angle measuring exactly 90 degrees.
- Obtuse Angle: An angle measuring greater than 90 degrees but less than 180 degrees.
- Straight Angle: An angle that measures exactly 180 degrees.
- Congruent Angles: Angles that have equal measures.
- Adjacent Angles: Two angles that share a common vertex and ray (side) but do not overlap.
- Angle Bisector: A ray that divides an angle into two congruent adjacent angles.
- Definitions and Postulates: Serve as foundational statements and beliefs that underpin geometric reasoning, essential for proving theorems.
- Number Line: A representation where each point is correlated to a specific number, and vice versa.
- Coordinate: A number that identifies a specific point on a line.
- Length of a Segment: Calculated as the absolute value of the difference between the coordinates of its endpoints.
- Segment Addition Postulate: If point B is between A and C, then the sum of segments AB and BC equals segment AC.
- Congruent Shapes: Objects sharing identical size and shape.
- Conditional Statement: Formulated as "If _ then _", serving as a logical assertion.
- Angle Addition Postulate: The measure of an angle formed with an interior point can be expressed as the sum of the measures of the two angles it creates.
- Angle Measurement: Angles are measured in degrees or radians.
- Sides of an Angle: Represented by the two rays forming the angle.
- Vertex of an Angle: The common endpoint of the rays that compose the angle.
- Complementary Angles: Pairs of angles that sum to 90 degrees.
- Supplementary Angles: Pairs of angles that sum to 180 degrees.
- Linear Pair: A pair of adjacent angles that are supplementary.
- Ruler Postulate: States that points on a line correspond with real numbers and establishes rules for measuring segments.
- Postulate on Lines and Plans: Specifies that through any two points, there exists one and only one line, and through any three non-collinear points, there exists exactly one plane.
- Postulate on Plane Intersection: If two planes intersect, their intersection will form a line.
- Theorems: Significant statements or propositions that have been rigorously proved based on previously established facts.
