week 10 module

Write a Swift playground program for three classes – a ‘Quadrilateral’, a ‘Parallelogram’ and a ‘Rectangle’ class – such that:

1. The ‘Quadrilateral’ is the base parent class and has four attributes for its four sides.
2. The ‘Parallelogram’ extends the ‘Quadrilateral’ class where two sets of sides are parallel to each other.
3. The ‘Rectangle’ extends the ‘Parallelogram’ where two adjacent sides are at right angles to each other.
4. You will need to define attributes for side lengths and angles to appropriately create each type of object.
   1. Quadrilateral needs 4 sides and 1 angle
   2. Parallelogram needs 2 sides and 1 angle
   3. Rectangle needs 2 sides and 1 angle which is 90 degrees
   4. This site is helpful in figuring out how to construct the shapes – http://www.ambrsoft.com/TrigoCalc/Quadrilateral/Shape1.htm
5. The sum of the four angles has to equal 360 degrees.
6. You may also need computed properties for area, perimeter and diagonals.
7. Demonstrate inheritance and polymorphism as applied to this set of classes. Assume any other properties or methods that may be useful to you in completing this assignment.
8. Document your code, please.
9. Also put comments in code where necessary to make it more descriptive
10. Format your console output in a clear to understand manner.

Upload your playground and a screenshot of the console window.
