  • 1. Geometry In The Real World
    By Nick Holt
    Block 1 A-day
    12/11/09
  • 2. Point
    An undefined term in geometry, it names a location and has no size
  • 3. Line
    An undefined term in geometry, a line is a straight path that has no thickness and extends forever.
  • 4. Plane
    An undefined term in geometry, it is a flat surface that has no thickness and extends forever.
  • 5. Angle
    A figure formed by two rays with a common endpoint.
  • 6. Perpendicular lines
    Lines that intersect at 90 degree angles.
  • 7. Parallel lines
    Lines in the same plane that do not intersect.
  • 8. Triangle
    A three sided polygon.
  • 9. Right Triangle
    A triangle with one right angle.
  • 10. Pentagon
    A five-sided polygon.
  • 11. Hexagon
    A six-sided polygon.
  • 12. Square
    A quadrilateral with four congruent sides and four right angles.
  • 13. Rectangle
    A quadrilateral with four right angles.
  • 14. Trapezoid
    A quadrilateral with exactly one pair of parallel sides.
  • 15. Parallelogram
    A quadrilateral with two pairs of parallel sides.
  • 16. Circle
    The set of two points in a plane that are a fixed distance from a given point called the center of the circle.
  • 17. Cylinder
    A three dimensional figure with two parallel congruent circular bases and a curved lateral surface that connects the bases.
  • 18. Sphere
    The set of points in space that are a fixed distance from a given point called the center of the sphere.
  • 19. Cube
    A prism with six square faces
  • 20. Regular pyramid
    A pyramid whose base is a regular polygon and whose lateral faces are congruent isosceles triangles.
  • 21. Right cone
    A cone whose axis is perpendicular to the base.
