### Educational Resource on Transformations: Rotation of Triangle ABC

#### Problem Statement

**Objective:**
To understand the concept of rotation in geometry by applying a 90-degree counterclockwise rotation to a triangle on a coordinate plane.

**Scenario:**
Triangle \( ABC \) is presented on a coordinate plane. The goal is to rotate this triangle 90 degrees counterclockwise around point \( A \) to form triangle \( A'B'C' \).

**Instructions:**

1. **Observe the Original Triangle:**
   - Triangle \( ABC \) is plotted on a coordinate graph with vertices:
     - \( A \) at (0, -3)
     - \( B \) at (2, 2)
     - \( C \) at (-3, -5)

2. **Perform the Rotation:**
   - Rotate triangle \( ABC \) 90 degrees counterclockwise about point \( A \). This rotation will change the positions of points \( B \) and \( C \) while keeping \( A \) fixed.

3. **Graphing the Rotated Triangle:**
   - Determine and plot the new positions of points \( B' \) and \( C' \) after rotation. 
   - Ensure that the points maintain their relative distances to point \( A \).

The graph contains:

- **Axes:** The horizontal axis represents the x-coordinate, and the vertical axis represents the y-coordinate.
- **Gridlines:** To assist with accurate plotting and measurement.
- **Triangle ABC:** Initially displayed with solid lines, showing its vertices and edges.

**Learning Outcomes:**

- Grasp the mathematical concept of geometric rotations.
- Develop skills in graphing transformations on the coordinate plane.
- Enhance spatial reasoning and visualization skills.
