how do you square an angle
Hold the pivot point against the board and move the square until your desired angle lines up with the edge of the board. It is important to note that the angle you need to find is actually the complement of the angle you need. For example, if you need a 60-degree angle, you need to find the 30-degree mark. This is the complementary angle because the two add up to 90 degrees. After you have found the correct angle, draw a line along the square. This mark can then be used to make a clean, proper cut as needed.
