Question

which defines a line segment?
○ two rays with a common endpoint
● a piece of a line with two endpoints
○ a piece of a line with one endpoint
○ all points equidistant from a given point

Explanation:

To determine the correct definition of a line segment, we analyze each option:

• "Two rays with a common endpoint" defines an angle, not a line segment.
• "A piece of a line with two endpoints" matches the definition of a line segment, as a line segment is a part of a line bounded by two distinct endpoints.
• "A piece of a line with one endpoint" defines a ray, not a line segment.
• "All points equidistant from a given point" defines a circle, not a line segment.

Answer:

a piece of a line with two endpoints
