  10. Unit 27 27.5 Mid-Points of Line Segments

  11. What are the coordinates of the mid-point of the line segment AB? The coordinates of A are (2, 7) and of B (5, 3) Hence the coordinates of the mid-point of AB are: Show this point on the diagram ? ? ? ? y A ? ? ? C B x D

  12. What are the coordinates of mid-point of the line segment AC? The coordinates of A are (2, 7) and of C (-5, 3) Hence the coordinates of the mid-point AC are: Show this point on the diagram ? ? ? ? y A ? ? ? C B x D

  13. What are the coordinates of mid-point of the line segment BD? The coordinates of B are (5, 3) and of D (-4, -5) Hence the coordinates of the mid-point BD are: Show this point on the diagram ? ? ? ? y ? ? A ? C B x D
