This C# program allows users to create and manipulate polygons using a graphical user interface. Users can input the center, length, number of edges, and rotation angle of the polygon through text boxes, visualize the polygon in a picture box, and rotate it as needed. The program also supports setting random values for ease.

# Polygon Drawer and Rotator

## Overview

This C# program allows users to create and manipulate polygons using a graphical user interface. The program consists of two main classes, `Point2D` and `Polygon`, and provides functionality to create, draw, and rotate polygons on a form. Users can input the center point, length, number of edges, and rotation angle of the polygon through text boxes, and visualize the polygon in a picture box.

## Classes

### Point2D Class

- **Data Members**: Cartesian coordinates (x and y)

- **Properties**: Accessor properties for x and y

- **Constructors**:

  - Default constructor

  - Constructor that sets initial 2D coordinates with random x and y values

- **Methods**:

  - `printCoordinates()`: Prints the coordinates of the 2D point

  - `calculatePolarCoordinates()`: Calculates polar coordinates (P(r,θ)) of the 2D point

  - `calculateCartesianCoordinates()`: Calculates Cartesian coordinates (P(x,y)) from polar coordinates

  - `printPolarCoordinates()`: Prints the pre-calculated polar coordinates of the 2D point

### Polygon Class

- **Data Members**: Center (Point2D), length, number of edges

- **Properties**: Accessor properties for length and number of edges

- **Constructors**:

  - Default constructor

  - Constructor that takes initial center and length as parameters

- **Methods**:

  - `calculateEdgeCoordinates()`: Calculates the vertex points of the polygon starting from a random point

  - `rotatePolygon()`: Recalculates the vertex points of the polygon in a clockwise direction

## GUI Elements

- **TextBoxes**:

  - Center of the polygon (range for x: [0,3], range for y: [0,3], default: (0,0))

  - Length of the polygon (range: [3-9], default: 4)

  - Number of edges of the polygon (range: [3-10], default: 5)

  - Angle of rotation (range: [0-359], default: 30)

- **ListBox**: Displays the edge coordinates in order

- **PictureBox**: Draws the graphics of the polygon

  - The center point of the polygon is the midpoint of the PictureBox

- **Buttons**:

  - **Draw Polygon**: 

    - Creates a polygon object based on the text box values (rotation angle is zero for the first draw)

    - Recalculates the edge coordinates

    - Draws the polygon in the PictureBox and lists the edge coordinates in the ListBox

  - **Rotate Polygon**: 

    - Rotates the drawn polygon based on the entered angle

    - Does nothing or gives a warning if no polygon is drawn

  - **Set Random Values**: Sets random values on all text boxes

## Usage

1. **Run the Program**: 

   - Open the project in your preferred C# IDE (e.g., Visual Studio).

   - Build and run the solution.

2. **Interface**:

   - Enter values for the center point, length, number of edges, and rotation angle in the respective text boxes.

   - Click "Draw Polygon" to create and draw the polygon.

   - The edge coordinates will be displayed in the ListBox.

   - Click "Rotate Polygon" to rotate the polygon based on the entered angle.

   - Click "Set Random Values" to populate the text boxes with random values.

## Notes

- Default and random values are provided for ease of use. If these values cause issues, feel free to use alternative values.

- The program uses the midpoint of the PictureBox as the center point for drawing the polygon.
