Question

Which figures can be precisely defined by using only undefined terms? Check all that apply. angle arc circle line segment parallel lines

Answer 1

circle, line segment, and parallel lines

Explanation:

A circle is the set of all points a given distance from a fixed point called a center. This only uses the undefined term "point."

A line segment is a portion of a line with two distinct endpoints. This uses the undefined terms "line" and "point."

Parallel lines are lines that never intersect. This uses the undefined term "line."

An angle is two rays joined at a common point called the vertex. While this does use the undefined term "point," it also uses the defined term "ray." This is not one of our options.

An arc is a portion of the circumference of a circle. This uses the term "circle," so it is not one of our options.

Answer 2

Angle, parallel lines figures which can be precisely defined by using only undefined terms angles and parallel lines.
