A square sha ed can be considered to be a specific the of a rectangle. This is a mationthip wo can $"$is$-$a$",$ where a square $"$is$-$a$"$ specific type of rectangle, particulariy Whent all $4$ sides are equal. in $\frac{?}{OO}P$ this relationship is called Inheritance.

The same idea we can follow for a circle. which $"$ls$-$a$"$ specific type of an oval.

We can aloo generalite where we can say all circles, ovals, squares and rectangles are Gifiereat kypets of shapes.

Hence, shape is a generaf class. But can you draw a shape without knowing what specific shuoe you want to draw? thus a shage is what we call in OOP an abstract class $-$ that is a class that cannot be instantiated.

However, in the spirit of programming in zoneral; we want to create a shape factory Where we can generate random shapes $($with valid dimensions, Le$.$ no negative or zero sides or radius, and keep max dirrension to $100,$ all integers$)$:

Furthermore, adding one twist. If we have a canvas object, one can say that the canvas contains shapes or "has$-$a$"$ ist of shapes associated with it$.$ This is a composition association in COP, where a canvas contains, or Thas$-$a$"$ shapc$($s$).$
