Question

which figures can be precisely defined by using only undefined terms? select three options. angle arc circle line segment parallel lines

Explanation:

• Angle: An angle is formed by two rays (which are defined using the undefined term of a point and a line).
• Circle: A circle is the set of all points in a plane that are at a given distance (radius) from a given point (center). Here, the undefined terms of a point and a plane are used.
• Line segment: A line segment is a part of a line that has two endpoints. The line is an undefined term, and the endpoints are points (another undefined term).

Answer:

angle, circle, line segment
