Question

which is precisely defined using the undefined terms point and plane? circle line segment perpendicular lines ray

Explanation:

• A circle is defined as the set of all points in a plane that are at a given distance (radius) from a given point (center).
• A line segment is defined using two points (its endpoints) but not the plane.
• Perpendicular lines are defined using the concept of angles (formed by two lines) and not directly using the plane in the core definition related to the given terms here.
• A ray is defined using a point (its endpoint) and a line (not the plane in the way required here).

Answer:

circle
