A point C is called the midpoint of a line segment AB, if
C is an interior point of AB
AC=CB
C is an interior point of AB such that AC=CB
AC+CB=AB
Explanation of the correct option
If C is the mid point of the line segment AB, then C is an interior point of AB such that AC=CB.
Hence, the correct option is (c).
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
In the above question, point C is called a mid-point of line segment AB, prove that every line segment has one and only one mid-point.
