definition of a line segment\tteachers comments
rubys definition: two points, call them end points, and all of the other points in a straight line between them.\tyour definition is kind of correct, but it lacks mathematical precision.
shriyas definition: a line between two points.\twunderbar! well done.
abhisheks definition: all of the points equidistant from some point p.\twere you thinking of a circle or perhaps a sphere?

Explanation:

A line - segment is a line between two points. Ruby's definition is imprecise as it doesn't clearly state the nature of the "straight line" between the endpoints. Abhishek's definition describes a circle (in 2 - D) or a sphere (in 3 - D) which is not a line - segment. Shriya's definition is the most accurate for a line - segment.

Answer:

Ruby's definition - Your definition is kind of correct, but it lacks mathematical precision.
Shriya's definition - Wunderbar! Well done.
Abhishek's definition - Were you thinking of a circle or perhaps a sphere?
