Answer:
The functions of the US Constitution are:
-to create a federal government.
-to protect the rights of US citizens.
-to divide power between federal and state governments.
Step-by-step explanation:
The Constitution of the United States, adopted on September 17, 1787 and ratified in 1788, establishes the basic political and legal framework of the United States. It provides for a federal republic in the form of a presidential system.
It prescribes a separation of powers known as "checks and balances", in which the organs of government, legislation and the judiciary act separately from one another and control each other through far-reaching entanglements.
The original constitutional text consists of seven articles. It was supplemented by 27 amendments over the course of two centuries, ten of which were added as Bill of Rights, guaranteeing citizens' rights in the nation.
