1. What is the difference between a line and a line segment?

• A line extends to infinity in both directions; a line segment is part of a line bound by two endpoints.
• A line extends to infinity in both directions; a line segment is part of a line that extends to infinity in only one direction and has an endpoint in the other direction.
• A line segment extends to infinity in both directions; a line is part of a line segment bound by two endpoints.
• A line segment extends to infinity in only one direction and has an endpoint in the other direction; a line is part of a line segment bound by two endpoints.

2. Which statement is true?

• A line is a finite portion of a finite line segment that is bound by two distinct endpoints.
