Draw Triangle Class - Object-Oriented Software Development - Engineering Assignment Help

Assignment Task:

Problem Description

Draw a circle with three random points on the circle. Connect the points to form a triangle. Display the angles in the triangle. Use the mouse to drag a point along the perimeter of the circle. As you drag it, the triangle and angles are redisplayed dynamically as shown in Figure 1.

You will need to create a DrawTriangle class (not main class) which takes some appropriate parameters in one of its methods to draw the triangle within the circle as shown in Figure 1. Your will not get full marks if DrawTriangle class is not created nor used as it as part of Object-Oriented Software Development.

What to submit:

Submit the 5 screenshots of the output along with a check list of the following steps using this word document and full NetBeans Project folder. Note, your project should be developed using NetBeans otherwise your work will not be marked.

Put this word document in your NetBeans project folder and then zip before submission.

1. Can your program display a circle in the centre of the frame, if not, why?

2. Can your program display three points on the circle, if not, why?

3. Can your program draw a triangle using these three points, if not, why?

4. Can your program compute the angles in the triangle, if not, why?

5. Can your program display the angles in the triangle, if not, why?

6. Note that three points are three small circles. Can your program detect which small circle is pressed by the mouse, if not, why? 

7. Can your program drag a small circle that has been pressed, if not, why?

8. Can your program drag a small circle along the perimeter of the circle, if not, why? (Hint: Ignore the mouse drag if it is not along the perimeter of the circle.)
