Is the following statement a good definition? why? a segment is part of a line. a. no, it is not. the statement is not precise. a ray or a point could be part of a line. b. no, it is not. the statement is too short to be a good definition. c. yes, it is. the statement is precise and reversible. d. yes, it is. all segments are parts of lines.

Option A is the correct option.

Step-by-step explanation:

We are given the definition, 'A segment is a part of a line'.

It is required to know whether this is a good definition or not.

Since, we know that,

'A segment is the part of line bounded by two distinct end points'.

Thus, the given definition is not precise as,

The segment many not be bounded, which then gives a ray.

The bounds may not be distinct points, which then gives a point.

Hence, the correct option is,

A. No, it is not. The statement is not precise. A ray or a point could be part of a line.
