which figures can be precisely defined by using only undefined terms? select three options.\nangle\narc\ncirc…

Brief Explanations:

Undefined terms in geometry are point, line, and plane.

• Angle: Defined using rays (which rely on lines/points, but rays are defined terms, so angle uses defined terms).
• Arc: Part of a circle, which requires the circle definition (uses defined terms like center/radius).
• Circle: Defined as the set of all points in a plane equidistant from a fixed point (center, a point; distance uses undefined terms implicitly but is a basic relation here—wait, correction: circle uses point (undefined) and distance (a defined term? No, actually, in basic geometry, circle is defined with point (undefined) and the concept of equidistant, but let’s check standard definitions:
• Line segment: Defined as part of a line between two points (both undefined terms: line, point).
• Parallel lines: Defined as lines in the same plane that never intersect (uses line (undefined) and plane (undefined)).
  Wait, standard correct ones: line segment (point, line), parallel lines (line, plane), circle (point, plane, distance—but wait, no: let’s confirm: Undefined terms are point, line, plane.
• Line segment: Two points (undefined) and a line (undefined) → yes, uses only undefined terms.
• Parallel lines: Two lines (undefined) in a plane (undefined) with no intersection → yes.
• Circle: Set of points (undefined) in a plane (undefined) equidistant from a fixed point (undefined) → yes, because all components are undefined terms (point, plane).
  Angle uses rays (defined as part of a line with an endpoint), so angle uses defined terms. Arc uses circle (which is okay, but wait no—arc is part of a circle, but the question is which can be defined using only undefined terms. So the three correct are circle, line segment, parallel lines.

Answer:

circle, line segment, parallel lines
