Question

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

Explanation:

In Euclidean Geometry, undefined terms are point, line, and plane. Parallel lines are defined using "line" (undefined). Angle uses rays (defined via "line" and "point", undefined). Line segment is part of a "line" between two "points" (undefined). Arc depends on circle (needs distance, defined), circle uses distance (defined).

Answer:

parallel lines, angle, line segment
