<span>The correct answers are circle, line segment and parallel lines.
Explanation:
The undefined terms of geometry are point, line and plane.
A circle is a set of points equidistant from a fixed point called the center; this uses no terms except the undefined terms.
A line segment is a part of a line with two distinct endpoints. Again, no terms used other than undefined terms.
Parallel lines are lines that never intersect; again, no terms other than undefined terms.</span>
