How to mark angles with a folding square?













Shop for Folding Squares 














When you need to mark out angles for different applications, for example when producing a mitre cut or joint then you will need to use angles of 45° and 90°. 









Step 1 – Position workpiece
Place your workpiece onto a flat surface (workbench). 









Step 2 – Choose angle
Place the angle of the folding square on the area of the workpiece you want to mark. 









Remember, if you are marking a 45° angle then you will need a locking folding square. Sliding folding squares that come with three different length sides (scalene triangle) do not contain angles of 45°. 









Step 3 – Line up angles
At the point you are going to mark an angle, line up the edges of the workpiece with the sides or bottom of the folding square that contains the angle. For a 45° angle, the bottom side needs to line up with the bottom side of the workpiece. The corner of the angle will need to be on the corner of the workpiece. 









For a 90° angle, the two sides that form the angle need to be parallel to the edges of the area you want to mark. 









Step 4 – Mark angles
Hold the folding square firmly against the workpiece and mark the right angle using a pencil. 









When marking a 45° angle, hold the folding square firmly and mark the angle using a pencil.
