Question

solid geometry deals with two - dimensional objects. true false 18. choose the best answer. which choice names a line segment? a b c (overrightarrow{bc}) (overleftrightarrow{ac}) (overline{ab}) (ab)

Explanation:

Step1: Recall solid geometry definition

Solid geometry deals with three - dimensional objects, not two - dimensional ones. So the statement "Solid geometry deals with two - dimensional objects" is false.

Step2: Recall line - segment notation

A line segment is denoted with a bar over the two endpoints. $\overrightarrow{BC}$ is a ray, $\overleftrightarrow{AC}$ is a line, and $AB$ is just the distance or name of the endpoints without indicating a segment. $\overline{AB}$ is the correct notation for a line segment with endpoints $A$ and $B$.

Answer:

1. B. False
2. C. $\overline{AB}$
