t parallel, we can pro-duce them and form a triangle in the one direction or the other; bythis figure we form the triangle BCE, whose area we may repre-sent by t. As B C, and the angles as B and C are all known, the triangleEB C is determined in all respects. As PB is known, PE is known, and… … DIVISION OF LANDS. 135 2t+2cmWhence, x=c^^TE We now have the numerical value of x, from which we subtractEC, and we have CG, which being measured from C will give thepoint G, through which to draw the line from P, to divide thefigure as required. Case 2. By a line making a given angle with one of…
