Explain how the u. s. constitution strengthened citizen's rights, national security, and the economy.

The U.S. Constitution strengthened citizen's rights with the Bill of Rights, which is a series of constitutional protections against government power.

It strengthened national security by giving powers to the central power to coordinate defense matters: the president is the chief in command of the U.S. military, and the U.S. Congress is authorized to issue defense spending, and to declare war.
