Question

which undefined term can contain parallel lines?
line
plane
point
ray

Explanation:

To determine which undefined term can contain parallel lines, we analyze each option:

• A line is a one - dimensional figure. Parallel lines are two lines, and a single line cannot contain two parallel lines.
• A plane is a two - dimensional flat surface that extends infinitely. In a plane, we can have two or more lines that are parallel (they never intersect and are coplanar).
• A point has no dimension, so it cannot contain any lines, let alone parallel lines.
• A ray is a part of a line with a fixed starting point and extending infinitely in one direction. A single ray cannot contain two parallel lines.

Answer:

B. plane
