Question

which is the definition of a line segment?
○ a figure formed by two rays that share a common endpoint
○ the set of all points in a plane that are a given distance away from a given point
○ a part of a line that has one endpoint and extends indefinitely in one direction
○ a part of a line that has two endpoints

Explanation:

• Analyze each option:
• First option: Defines an angle (two rays with common endpoint).
• Second option: Defines a circle (set of points at given distance from a point).
• Third option: Defines a ray (part of line with one endpoint, extends infinitely).
• Fourth option: Matches the definition of a line segment (part of line with two endpoints).

Answer:

D. a part of a line that has two endpoints (assuming the last option is labeled D; if labels are A - D as per order: A. a figure formed by two rays that share a common endpoint, B. the set of all points in a plane that are a given distance away from a given point, C. a part of a line that has one endpoint and extends indefinitely in one direction, D. a part of a line that has two endpoints, then the answer is D. a part of a line that has two endpoints)
