A recursive function always has to say when to stop repeating itself. Also, other stuff. The condition that terminates the further call of the function by defining the termination state is called the base condition.

It starts with a number that we want to know, It keeps on multiplying by smaller and smaller numbers. Most people dont know how to interpret all the lines, angles and numbers, so it would be a waste of time for an architect to get into the details about how they measured the spacing.
