What is a good example of the principle of checks and balances

Essentially, the principle of checks and balances come in with the government. The role of checks and balances is to ensure that no single branch becomes to strong and unstoppable. The easiest example is the government itself. Shown in the picture attached (credit to Whomever created it), It shows that each portion of government is assigned a certain role to ensure no branch has more power over the others.

In my honest opinion , i’d say franklin d roosevelt was a president that impacted our nation , i say this because fdr is voted among top three best us presidents and he was the longest serving president by 3 terms , usually presidents only supposed to have two terms increments of 4 years , equivalent to 8 years total before election time. and he established the fdic , through the 1933 banking act and he established the us , social security system , during his presidency, and established a national minimum wage , through the fair labor standards act , fdr led the allied coalition to victory in wwii and he played a major role in the creation of the united nations.
