Side 245 - All the interior angles of any rectilineal figure, together with four right angles, are equal to twice as many right angles as the figure has sides.
Side 42 - From eight times the chord of half the arc, subtract the chord of the whole arc, and divide the remainder by 3, and the quotient will be the length of the arc, nearly.
Side 185 - ... the breadth, the remainder shall be esteemed the just length of the keel to find the tonnage ; and the breadth shall be taken from the outside of the outside plank in the broadest place in the ship, be it either above or below the main wales...
Side 162 - PAINTERS' WORK. PAINTERS' work is computed in square yards. Every part is measured where the colour lies ; and the measuring line is forced into all the mouldings and corners. Windows are done at so much a piece. And it is usual to allow double measure for carved mouldings, &c.
Side 50 - BAC is cut off from the given circle ABC containing an angle equal to the given angle D : Which was to be done. PROP. XXXV. THEOR. If two straight lines within a circle cut one another, the rectangle contained by the segments of one of them is equal to the rectangle contained by the segments of the other.
Side 3 - The circumference of every circle is supposed to be divided into 360 equal parts, called degrees ; and each degree into 60 equal parts, called minutes ; and each minute into 60 equal parts, called seconds ; and these into thirds, etc.
Side 6 - The diameter of a circle is a straight line passing through the center, and terminated, both ways, by the circumference.
Side 95 - Rule 2. From three times the diameter of the sphere subtract twice the height of the segment; multiply this remainder by the square of the height and the product by 0.5236.
Side 133 - Rule. Set 12 on B to the breadth in inches on A ; then against the length in feet on B, is the content on A> in feet and fractional parts.
