![### Construction of Triangle Using Compass and Straightedge
#### Problem Statement:
**6. Use your compass and straightedge to construct triangle \( \triangle A'B'C' \) such that \( D_{P,3}(\triangle ABC) = \triangle A'B'C' \).**
#### Description:
You are provided with an initial triangle \( \triangle ABC \) and a point \( P \) as shown in the diagram. The task is to construct a new triangle \( \triangle A'B'C' \) by performing a specific geometric transformation.
#### Diagram Explanation:
The diagram accompanying the problem consists of the following elements:
- A triangle \( \triangle ABC \) with vertices labeled as \( A \), \( B \), and \( C \).
- A point \( P \) outside the triangle \( \triangle ABC \).
- The problem requires constructing a triangle \( \triangle A'B'C' \) such that it fulfills the condition \( D_{P,3}(\triangle ABC) = \triangle A'B'C' \).
#### Steps for Construction:
1. **Identify Vertices:** Clearly mark the points \( A \), \( B \), and \( C \) on your paper.
2. **Draw Line Segments:** Using your straightedge, connect the points \( A \) to \( B \), \( B \) to \( C \), and \( C \) to \( A \) forming \( \triangle ABC \).
3. **Locate Point \( P \):** Place point \( P \) in the appropriate position as indicated in the diagram.
4. **Use Compass for Transformation:**
- Set your compass width to a certain proportional distance (based on the specific conditions of the transformation \( D_{P,3} \)).
- Rotate and translate each vertex of \( \triangle ABC \) with respect to point \( P \), preserving the specified relationship.
5. **Construct \( \triangle A'B'C' \):**
- Mark the new vertices \( A' \), \( B' \), and \( C' \) at the determined locations after the transformation.
- Connect these vertices using your straightedge to complete \( \triangle A'B'C' \).
#### Understanding \( D_{P,3} \):
- \( D_{P,3} \) represents a dilation of scale factor 3 centered at point \( P \).
