Segments, Rays,
& Distance


    Section 1-3
And Now, for Some New Definitions

 Segment – two points on a line and all the
     points between them

               B                    C
           Segment BC, or… BC

    B and C are the endpoints of BC.

  In geometry, between means “on the line connecting.”
More New Definitions

Ray – one point on a line and all the points
     extending in one direction only

           C             K
         Ray CK, or… CK          (not KC!!!)
               C is the endpoint of CK.
More New Definitions

Opposite rays – rays that extend in opposite
 directions along the same line from a
 common endpoint

             X      Y         Z

         YX and YZ are opposite rays.
More New Definitions

 Length – the distance from one point to another
            X       W              Y Z
            •        •             •      •
       -7 -6 -5 -4 -3 -2 -1 0 1   2 3 4   5 6   7 8


     The length of XY is denoted XY.
 To find lengths on a number line, take the absolute
 value of the difference of the coordinates of the endpts.:
 XY = 3−(−5) =8                     OR            XY = −5−3 =8
                Distance must be positive.
More New Definitions


 Postulates – statements accepted
    without proof; also called axioms

Congruent – having the same size
   and shape
    congruence symbol:
More New Definitions

Congruent Segments – segments of equal length
                   •N
           10 cm         P•   10 cm
                                      •M

          L•
               To show congruence
                  in the diagram
   The segments have           Which means that they
   equal lengths:              are congruent:
       LN = MP                     LN = MP
More New Definitions

Midpoint of a Segment – point that divides a
    segment into two congruent segments
          •           •          •
         A            B          C

       If AB = BC, then
             B is the midpoint of AC.
One More Definition


Segment Bisector – a line, segment,
   ray, or plane that intersects a
   segment at its midpoint
Let’s Practice!!!

Look to your textbooks, page 14, #1-14

Section1.3a

  • 2. And Now, for Some New Definitions Segment – two points on a line and all the points between them B C Segment BC, or… BC B and C are the endpoints of BC. In geometry, between means “on the line connecting.”
  • 3. More New Definitions Ray – one point on a line and all the points extending in one direction only C K Ray CK, or… CK (not KC!!!) C is the endpoint of CK.
  • 4. More New Definitions Opposite rays – rays that extend in opposite directions along the same line from a common endpoint X Y Z YX and YZ are opposite rays.
  • 5. More New Definitions Length – the distance from one point to another X W Y Z • • • • -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 The length of XY is denoted XY. To find lengths on a number line, take the absolute value of the difference of the coordinates of the endpts.: XY = 3−(−5) =8 OR XY = −5−3 =8 Distance must be positive.
  • 6. More New Definitions Postulates – statements accepted without proof; also called axioms Congruent – having the same size and shape congruence symbol:
  • 7. More New Definitions Congruent Segments – segments of equal length •N 10 cm P• 10 cm •M L• To show congruence in the diagram The segments have Which means that they equal lengths: are congruent: LN = MP LN = MP
  • 8. More New Definitions Midpoint of a Segment – point that divides a segment into two congruent segments • • • A B C If AB = BC, then B is the midpoint of AC.
  • 9. One More Definition Segment Bisector – a line, segment, ray, or plane that intersects a segment at its midpoint
  • 10. Let’s Practice!!! Look to your textbooks, page 14, #1-14
