What relationships exist between super and sub classes?

• How can we use superclasses to improve ourInteractiveMath2 code?
  • To be implemented in  computeNetArea() method
  • How can an element in the Polygon2 ‘ list that  is a RightTriangle2 call the getHypotenuse() method?
    • To be implemented in the new method void printDetails() which should , among other , things print the hypotenuse length for any RightTriangle2’s?
• What is Inherited by subclasses?
  • Constructors?
  • instance variables
  • static variables?
