    Study Notes

    Geometry Terms

    • Point: A specific location represented by a dot and typically labeled with a letter.
    • Line: An infinite straight path extending in both directions, named using two points on the line.
    • Line Segment: A part of a line defined by two endpoints, named after these endpoints.
    • Ray: A line segment with one endpoint that extends infinitely in one direction, named starting with the endpoint.
    • Plane: An infinite flat surface named by three distinct points within it.
    • Intersecting Lines: Lines that cross each other at one or more points.
    • Parallel Lines: Lines that remain equidistant and never meet or diverge.
    • Perpendicular Lines: Lines that intersect to form right angles (90 degrees).

    Angles

    • Degrees: Units used for angle measurement.
    • Right Angle: An angle measuring exactly 90 degrees.
    • Acute Angle: An angle that measures less than 90 degrees; considered 'small'.
    • Obtuse Angle: An angle that exceeds 90 degrees; characterized as 'large'.
    • Straight Angle: An angle measuring 180 degrees, appearing as a straight line.
    • Interior Angle: An angle located inside a shape.
    • Exterior Angle: An angle located outside a shape.
    • Complementary Angles: Two angles that sum to 90 degrees.
    • Supplementary Angles: Two angles that sum to 180 degrees.

    Triangles

    • Equilateral Triangle: A triangle with all sides of equal length.
    • Isosceles Triangle: A triangle with two sides of equal length.
    • Scalene Triangle: A triangle with no sides of equal length.
    • Right Triangle: A triangle that includes a 90-degree angle.
    • Acute Triangle: A triangle with three angles each measuring less than 90 degrees.
    • Obtuse Triangle: A triangle containing one angle greater than 90 degrees.

    Polygon Basics

    • Polygon: A shape with at least three straight sides, with no gaps or curves.
    • Quadrilateral: A polygon with four sides.
    • Regular Polygon: A polygon with all sides and angles congruent.
    • Irregular Polygon: A polygon made up of sides of different lengths and angles.
    • Specific Polygon Names:
      • Pentagon: Five sides.
      • Hexagon: Six sides.
      • Heptagon: Seven sides.
      • Octagon: Eight sides.
      • Nonagon: Nine sides.
      • Decagon: Ten sides.
      • Undecagon: Eleven sides.
      • Dodecagon: Twelve sides.

    Circles

    • Center of a Circle: The point equidistant from all points on the circumference.
    • Radius: A line segment from the center to any point on the circle.
    • Diameter: A line segment passing through the center, connecting two points on the circle.
    • Chord: A line segment connecting two points on the circle, not necessarily passing through the center.
    • Central Angle: An angle whose vertex is positioned at the center of the circle.
    • Circumference: The total distance around a circle.

    Symmetry

    • Line Symmetry: Occurs when a shape can be divided along a line such that both halves are congruent.
    • Rotational Symmetry: When a shape can be rotated less than 360 degrees and appear unchanged.
