Explanation:
A Constitution refers to a set of written laws and principles which is typically used to determine the power and authority of the government, as well as guarantee the fundamental rights of its citizens.
Basically, the Constitution accords powers to the national or federal government and these includes; enumerated or delegated, reflected, and concurrent powers.
Checks and balances refers to a system that is typically used in a democratic society to enforce a balance of power between the three (3) arms of government; executive, judiciary and legislative arm. These checks and balances are really important and necessary so as to ensure there wouldn't be an abuse of power by any of the arm of government.
A Supreme Court refers to a federal court and is typically the highest court in relation to the hierarchy of courts in the judicial branch. It is also referred to as the ap-ex court. Generally, it comprises of nine (9) justices (a chief justice and eight (8) associate justices). These nine (9) justices are appointed only by the president and subsequently confirmed by the senate after screening them diligently.
The president is empowered by the constitution to sign (veto) legislations, draft and initiate a budget plan, adjourn or convene the legislative body (Congress), grant state pardons and reprieve to citizens, command the armed forces, and welcome ambassadors representing other countries.
