Oblique lines change their distance, and would meet, if produced on the side of the least distance.
Σελίδα 75 - At a given point A, in a line AB, to make an angle equal to a given angle C. From the centres A and C, with any one radius, describe the arcs DE, FG. Then, with radius DE, and centre F, describe an arc, cutting FG in G. Through G draw the line AG, and it will form the angle required.
Σελίδα 113 - GLAZIERS' WORK. GLAZIERS take their dimensions, either in feet, inches, and parts, or feet, tenths, and hundredths. And they compute their work in square feet. ' In taking the length and breadth of a window, the cross bars between the squares are included. Also windows of round or oval forms are measured as square, measuring them to their greatest length and breadth, on account of the waste in cutting the glass.
Σελίδα 73 - The areas of circles are to each other as the squares of their diameters.
