classify each figure as a line, ray, or line segment. then, show how to write it.\n(a)\n(b)\n(c)
Answer
Explanation:
Step1: Recall definitions
A line extends infinitely in both directions, a ray extends infinitely in one - direction starting from a point, and a line segment has two endpoints.
Step2: Analyze figure (a)
It has one endpoint (E) and extends infinitely in one direction, so it is a ray. It is written as $\overrightarrow{EF}$.
Step3: Analyze figure (b)
It extends infinitely in both directions, so it is a line. It is written as $\overleftrightarrow{AB}$.
Step4: Analyze figure (c)
It has two endpoints (C and D), so it is a line segment. It is written as $\overline{CD}$.
Answer:
(a) Type: ray, How to write it: $\overrightarrow{EF}$ (b) Type: line, How to write it: $\overleftrightarrow{AB}$ (c) Type: line segment, How to write it: $\overline{CD}$
