Educational worksheet for identifying points, line segments, lines, and rays.

Problem Overview:

The task is to identify whether each given figure represents a point, line segment, line, or ray and to name it accordingly. The worksheet provides definitions for each term and an example to guide the solution.

#### Definitions Recap:
1. Point: A location in space, represented by a dot. Named with a single capital letter (e.g., \( A \)).
2. Line Segment: A straight path between two points, including the endpoints. Named using the two endpoints (e.g., \( \overline{AB} \) or \( \overline{BA} \)).
3. Line: A straight path that extends infinitely in both directions. Named using any two points on the line (e.g., \( \overleftrightarrow{CD} \)).
4. Ray: A straight path that starts at one point (the endpoint) and extends infinitely in one direction. Named starting with the endpoint (e.g., \( \overrightarrow{EF} \)).

#### Steps to Solve:
For each figure:
1. Identify the type of geometric object based on its characteristics:
- Does it have endpoints?
- Does it extend infinitely in one direction or both directions?
2. Name the object according to the rules provided in the definitions.

Solutions:

#### 1. Figure 1:
- Description: A straight path with two endpoints labeled \( C \) and \( D \).
- Type: Line segment.
- Name: \( \overline{CD} \) or \( \overline{DC} \).

#### 3. Figure 3:
- Description: A single point labeled \( Q \).
- Type: Point.
- Name: \( Q \).

#### 4. Figure 4:
- Description: A straight path extending infinitely in one direction, starting at point \( R \) and continuing through point \( S \). There is an arrow at the end opposite \( R \).
- Type: Ray.
- Name: \( \overrightarrow{RS} \).

#### 5. Figure 5:
- Description: A straight path with two endpoints labeled \( N \) and \( O \).

#### 7. Figure 7:
- Description: A straight path extending infinitely in both directions, with arrows at both ends. Points \( H \) and \( I \) are marked on the line.
- Type: Line.
- Name: \( \overleftrightarrow{HI} \) or \( \overleftrightarrow{IH} \).

#### 8. Figure 8:
- Description: A straight path extending infinitely in one direction, starting at point \( J \) and continuing through point \( K \). There is an arrow at the end opposite \( J \).
- Type: Ray.
- Name: \( \overrightarrow{JK} \).
