The Square consiste of a shortthick piece called the stock, with alonger, thinner piece at one end, andat right angles to it, called the stock projects beyond the sidesof the blade, and the tool can beeasily applied to the straight edge ofa piece of wood, that lines may bedrawn on the surface at right anglesto this straight edge. All the anglesof the square, exterior as well asinterior, must be perfect right is not only essential for theoperation just described, but also Fig. 27.
