Describe how to set adjust tools such as squares and protractors?

To adjust tools like squares and protractors, first ensure they are clean and free of debris. For a square, align one edge with a straight reference line and check for gaps; if misaligned, gently adjust the square until it fits perfectly. For a protractor, verify that the baseline is level and the center point aligns with the vertex of the angle you're measuring; if necessary, recalibrate the protractor by adjusting the pivot point. Regularly check these tools for accuracy to maintain precision in your work.
