A point C is called the midpoint of a line segment ¯¯¯¯¯¯¯¯AB if
(a) C is an interior of AB
(b) AC=CB
(c) C is an interior point of AB such that ¯¯¯¯¯¯¯¯AC=¯¯¯¯¯¯¯¯CB
(d) AC+CB=AB
Draw any line segment, say ¯¯¯¯¯¯¯¯AB. Take any point C lying in between A and B. Measure the lengths of AB,BC, and AC. Is AB=AC+CB?
[Note: If A,B,C are any three points on a line, such that AC+CB=AB, then we can be sure that C lies between A and B.]
