    Study Notes

    Definitions and Concepts

    • Area: Represents the total number of square units needed to cover a given surface.
    • Blueprint: A detailed plan that outlines the design or structure of an object or space.

    Coordinate Geometry

    • Coordinates: Ordered pairs (x, y) that pinpoint locations on a coordinate plane.
    • Distance: Measures the length of the straight path between any two points in a plane.
    • Distance Formula: The mathematical expression ( d = \sqrt{(x₂ - x₁)² + (y₂ - y₁)²} ) calculates distance based on coordinates.

    Line Segments and Relationships

    • Intersection: The specific point where two lines meet or cross.
    • Line Segment: A portion of a line defined by two distinct endpoints.
    • Midpoint: The exact point that divides a line segment into two equal parts.

    Lines and Angles

    • Parallel Lines: Lines located in the same plane that will never cross each other.
    • Perimeter: The total length around a geometric figure.
    • Perpendicular Lines: Lines that cross each other and create right angles.

    Mathematical Concepts

    • Phenomena: Observable occurrences or facts within the field of study.
    • Proof: A structured logical argument that confirms the validity of a statement or theorem.
    • Reciprocal: The inverse of a fraction, which when multiplied by the original yields a product of one.

    Slope and Theorems

    • Slope: Calculated as "rise over run," indicating the steepness and direction of a line on a graph.
    • Theorem: A statement that has been established to be true through logical reasoning and evidence.
    • Vertices: Points where two sides of a polygon or three edges of a space figure converge.
