17 Combining Line Segments, End-to-End Again, an important property of a line segment is that it begins and ends. In the drawing the line begins at point A and ends at point B . Also there is the related line segment that begins at point B and ends at point A . ____________________________________________________________________________________ Sometimes it is desired to combine two neighboring line segments that share an endpoint and that both lie on the same mathematical straight line. If the second line segment begins at point B (the one shared with segment ) we use C to designate the endpoint of the second segment. The combined line segment then begins at A and ends at C and we name it . Drawn as a graph this is shown as: C . B . A . _______________________________________________________________ Saxon Lesson Learning Concept Statement Number Concept Name Description (answers what is this concept?) Question (among many) Correct Answer 1 14 Combined line segments. Two elemental line segments AB and BC combine to make line segment AC. What line segment is formed from the combination of AB and BC? AC BA AB AC Click me for video > QuickTimeª and a decompressor are needed to see this picture. 17
18 Length of Combined Line Segment A property of a straight line is that the length of a combined line segment is the sum of the component lengths. We also note that the concepts of distance and length are the same for straight lines. However, when a line is curved the length (measured along the line) and the distance (measured along a straight line connecting the two end-points are generally different with the length greater than the distance. Homework: LCS 1 – 15 Please complete all of the problems in Problem Set 1 in the Saxon text on page 3. Do numbers 1 through 30. Saxon Lesson Learning Concept Statement Concept Name Description (answers what is this concept?) Question (among many) Correct Answer 1 15 Length of combined line segment. The length of AC (formed from segments AB and BC) is l(AC) = l(AB) + l(BC) What is length of combined line segments? l(AC) = l(AB) + l(BC) Click me for video > QuickTimeª and a decompressor are needed to see this picture.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
