Question

three students attempt to define what a line segment is. can you match the teachers comments to the definitions? definition of a line segment teachers comments rubys definition: two points, call them end points, and all of the other points in a straight line between them. were you thinking of a circle or perhaps a sphere? shriyas definition: a line between two points. wunderbar! well done. abhisheks definition: all of the points equidistant from some point p. your definition is kind of correct, but it lacks mathematical precision.

Explanation:

Ruby's definition is correct and precise for a line - segment. Shriya's is also correct but less detailed. Abhishek's definition describes points equidistant from a point which is the definition of a circle (in 2 - D) or a sphere (in 3 - D), not a line - segment. So, Ruby's definition matches "Wunderbar! Well done.", Shriya's matches "Your definition is kind of correct, but it lacks mathematical precision.", and Abhishek's matches "Were you thinking of a circle or perhaps a sphere?".

Answer:

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