    1 2 Points, Lines, And Planes 1 2 Points, Lines, And Planes Presentation Transcript

    • 1-2 Points, Lines, and Planes
      L.E.Q. How do you explain the basic terns and postulates of geometry?
    • A location.
      Without size.
      Represented by a dot.
      Named by a capital letter.
      What is a point?
      “Point A”
    • The set of all points.
      What is space?
    • A series of points that extends in two opposite directions without end.
      You can name a line by any two points on the line with a little line symbol above them.
      What is a line?
      A
      B
    • Points that lie on the same line.
      What does it mean to say collinear?
      We would say that points A, B, C, and D are collinear.
    • Are points U, V, and P collinear? If they are, what line do they fall on?
      Name another set of collinear points.
      EXAMPLE 1: Identifying Collinear Points.
    • What is a plane?
      It is like a flat surface that extends infinitely along its length and width.
      It has no thickness.
    • Points and lines in the same plane.
      What does it mean to say that figures are coplanar?
      Points G and O are coplanar.
    • Name the plane represented by the front of the cube.
      Name the top plane.
      Name the left plane.
      Name a diagonal plane.
      EXAMPLE 2: Naming a Plane.
    • An accepted statement of fact.
      What is a postulate/axiom?
    • Through any 2 points there is exactly ______ line.
      Postulate 1-1
    • If 2 lines intersect, then they intersect in exactly ______ __________.
      Postulate 1-2
    • If two planes intersect, then they intersect in exactly ______ _________.
      Postulate 1-3
    • Through any three noncollinear points there is exacly ______ _________.
      Postulate 1-4
    • Explain how a postulate and a conjecture are different.
      Closure:
    • Pgs 13 – 15 #s 2 – 66 even.
      Homework:
