regardless whether it complete or incomplete, correct or incorrect)
2. Fill in self-evaluation:
1. Can your program create the UI? _______________
2. Can your program display one polygon correctly? _______________
3. Can your program display n-side polygon correctly? _______________

Solution Code:
import javafx.application.Application;
borderPane.setBottom(hBox);
// Create a scene and place it in the stage
Scene scene = new Scene(borderPane, paneWidth, paneHeight);
private void paint() {
ObservableList<Double> list = polygon.getPoints();
list.clear();
