+## Jart
+
+### Instructions
+The purpose of this exercise is to create an image like the example below:
+
+![example](example.png)
+
+
+You will need to do the following:
+
+- Copy the code in the [usage](#usage) to your `Main.java`
+
+You'll define the logic for creating and working with shapes in the geometrical_shapes package. Create the following interfaces:
+
+- Drawable which contains the methods draw and getColor.
+
+- Displayable which contains the methods display and save.
+
+Define them according to the way they are called in the Main.java function.
+
+In order to compile and run `Main.java`, you'll need to define some classes. You are free to implement all the shapes with whatever internal structure you see fit, but you must provide a constructor for all the shapes, which will be described below:
+
+- `Point`: a new point should be created from two int values.
+- `Line`: a new line should be created from references to two different points.
+- `Triangle`: a new triangle should be created from references to three different points.
+- `Rectangle`: a new rectangle should be created from references to two different points.
+- `Circle`: a new circle should be created from a reference to a point representing the center, and an int value representing the circle's radius.
+
+
+You'll also need to create the `random` method for `Line`, `Point`, and `Circle`. You should derive their signatures from the usage.
+
+### Bonus
+You may optionally implement the following shapes, including the classes and interfaces needed to draw them:
+
+- Pentagon
+- Cube
+
+### Usage
+
+```java
+interface Displayable {
+    void display(int x, int y, Color color);
+    void save(String string);
+}
+
+interface Drawable {
+    void draw(Displayable displayable);
+    Color getColor();
+}
+
+public class Main {
+    public static void main(String[] args) {
+        Image image = new Image(1000, 1000);
+        Rectangle rectangle = new Rectangle(new Point(50, 50), new Point(300, 200));
+        rectangle.draw(image);
+        Triangle triangle = new Triangle(new Point(100, 100), new Point(900, 900), new Point(100, 900));
+        triangle.draw(image);
+
+        for (int i = 0; i < 50; i++) {
+            Circle circle = Circle.random(image.getWidth(), image.getHeight());
+            circle.draw(image);
+        }
+        image.save("image.png");
+    }
+}
+```
