Question

4 multiple choice 1 point if a rocket was launched into space and it continued forever on a straight path, the path could be considered a _________. rectangle line ray line segment 5 multiple choice 1 point given that \\(\overrightarrow{de}\\) is a perpendicular bisector of \\(\overline{ab}\\), which of the following is true? \\(ce = bc\\) \\(cd = ce\\) \\(m\angle bce=90^{circ}\\) c is the mid - point of \\(\overline{de}\\)

Explanation:

Step1: Recall geometric - figure definitions

A rectangle is a four - sided polygon. A line extends infinitely in both directions. A ray has one endpoint and extends infinitely in one direction. A line segment has two endpoints. The rocket's path starts from the launch point and extends infinitely in one direction, so it is a ray.

Step2: Recall properties of perpendicular bisectors

A perpendicular bisector of a line segment is perpendicular to the line segment and divides it into two equal parts. If $\overleftrightarrow{DE}$ is the perpendicular bisector of $\overline{AB}$, then the angle formed between $\overleftrightarrow{DE}$ and $\overline{AB}$ is a right angle. So, $m\angle BCE = 90^{\circ}$.

Answer:

1. C. ray
2. C. $m\angle BCE = 90^{\circ}$
