Problem Analysis:
The task involves identifying and labeling geometric figures as
lines,
line segments, or
rays based on their characteristics. Additionally, the student is asked to draw examples of each type.
#### Definitions Recap:
1.
Line: A straight path that extends infinitely in both directions.
- Characteristics: Has arrows on both ends.
2.
Line Segment: A part of a line with two endpoints.
- Characteristics: Has no arrows; it starts and ends at fixed points.
3.
Ray: A part of a line that starts at a point and extends infinitely in one direction.
- Characteristics: Has an arrow on one end and a point on the other.
Step-by-Step Solution:
#### Part 1: Labeling the Figures
We will analyze each figure in the grid and determine whether it is a
line,
line segment, or
ray.
1.
First Row:
-
Figure 1: Has an arrow on one end and a point on the other.
Label: Ray
-
Figure 2: Has arrows on both ends.
Label: Line
-
Figure 3: Has an arrow on one end and a point on the other.
Label: Ray
2.
Second Row:
-
Figure 4: Has arrows on both ends.
Label: Line
-
Figure 5: Has no arrows; it has endpoints on both sides.
Label: Line Segment
-
Figure 6: Has arrows on both ends.
Label: Line
3.
Third Row:
-
Figure 7: Has an arrow on one end and a point on the other.
Label: Ray
-
Figure 8: Has arrows on both ends.
Label: Line
-
Figure 9: Has an arrow on one end and a point on the other.
Label: Ray
#### Final Labels for the Grid:
```
Row 1: Ray, Line, Ray
Row 2: Line, Line Segment, Line
Row 3: Ray, Line, Ray
```
#### Part 2: Drawing Examples
The student is asked to draw examples of a
line,
line segment, and
ray.
1.
Line: Draw a straight path with arrows on both ends to indicate it extends infinitely in both directions.
2.
Line Segment: Draw a straight path with two endpoints (no arrows).
3.
Ray: Draw a straight path with an arrow on one end and a point on the other end to indicate it extends infinitely in one direction.
Final Answer:
```
Row 1: Ray, Line, Ray
Row 2: Line, Line Segment, Line
Row 3: Ray, Line, Ray
Drawings:
- Line: ↔
- Line Segment: ——
- Ray: →
```
Boxed Final Answer:
\[
\boxed{
\text{Row 1: Ray, Line, Ray} \\
\text{Row 2: Line, Line Segment, Line} \\
\text{Row 3: Ray, Line, Ray}
}
\]
