How would you make up a builders square on site in short explanation? ?

To make up a builder's square on site, you would need a straight piece of wood or metal that is at least 1 meter long. Place one end of the square against a straight edge, such as a wall or another piece of wood, and mark a right angle at the other end. Use a measuring tape to ensure that the two sides of the square are equal in length. Finally, use a saw to cut along the marked line to create a perfect right angle.

1. Draw a line approximately 3' long.
2. From one end, measure 6' and mark it.
3. From the other end, measure 8' and mark it.
4. Join the 6' and 8' marks.
5. The resulting triangle is a 3-4-5 right triangle, with the 3' side opposite the 90 degree angle.
