To check and see if a sheet is cut square.



1. Go to any corner and select a pivot point shown by the ARROW and put an X.

2. Using a trammel or large compass, scribe Arcs A, B on the bottom edge and C as shown, all with the same setting on the trammel or compass.

3. Using a straight edge draw a line thru the pivot point and where Arc B meets the edge of the sheet so the line crosses Arc A.

4. Using the straight edge again, draw a line thru where C meets the edge and where the first line and Arc A cross.

This will be a perfect square.

To Layout a Circle using a square:



1. Drive small brads the Diameter of the Circle, points "A" and "B".

2. Place the body of your Square across the points as shown.

3. Holding the point of your Pencil at Point "C" where the Tongue and the Body meet, slowly move the square, keeping the Square touching points "A" and "B".

You can draw up to a 14 inch Circle this way and a Larger one by flipping the square and drawing from both sides.
