c = Circle(float(r))
c.area()

1. Create a parent class Shape
   Only define the def area() interface function

2. Create a child/inherited class of Shape
   For example Triangle
   Define how Triagle is constructed (example below)
   a, b, c
   assert that it is a valid triangle
   assert a+b > c (do this 3 times)
   Define how area() is correctly calculated
   Test out the definition of a Triangle + correct area calculated

3. do the above for 3 more shapes
