Answer: Angle, circle, line segment, parallel lines can be precisely defined by using only undefined terms.
Step-by-step explanation:
In geometry , simple definitions of the given terms are as follows:
Line segment - A line with two end points.
Parallel lines - Two lines which never intersect.
Circle -A circle is the set of all points which are equidistant from a given point known as center of circle.
Arc - A curved line that is part of the circumference of a circle.
Angle - A shape, formed by two lines diverging from a common point .
Here all can be precisely defined by using only undefined terms except an arc.
Therefore, an angle, circle, line segment, parallel lines can be precisely defined by using only undefined terms.
