Why is the square used for trials of a fellow craft?

In Freemasonry, the square represents the importance of moral conduct and ethical behavior, which are crucial principles for a Fellow Craft. This tool teaches members to refine their character and conduct themselves with integrity, ensuring that their actions are squared with virtue and righteousness. Additionally, as a working tool, the square emphasizes the necessity of balancing personal interests with the greater good of the community, reinforcing the idea that a Fellow Craft must strive for both personal improvement and the welfare of others.
