Squaring the Foundation

and the square root of 100 is 10. Should the 

 10 -foot measure be longer than from 6 to 8, 

 the stake D is moved to the left until the pole 

 reaches from 6 to 8 ; if the measure is too short 

 to reach from 6 to 8, the stake is moved to the

right. All of these measurements should be 

 gone over two or three times, as in moving the 

 stake the lines may stretch or shrink. Either a 

 pin or a pencil mark may be used to indicate 

 the measurements on the lines at 6 and 8. 



If the building is to be 26 feet deep, that 

 distance is measured on the line CD and the 

 same distance from the line AB. Stakes are 

 then driven and a line drawn from E to F, and 

 in like manner a line is drawn from G to H. 

 The work is verified by squaring the last angle 

 as in the first case. The eight dots represent
