Answer:
Providing guides and limits to the governments power.
Step-by-step explanation:
The US Constitution has 7 articles which concern the power of the government, they talk about the three branches - legislative, executive and judiciary - of government and the amount of power each branch has.
The Constitution even created the check and balances system that create a complex system that interrelates each branch that has overlapped powers. This was designed so no branch could have too much power and could be contained by the other branch.
