3. Part 3If an extremity of the curve, as _B_, is not in a side of the rectangle, let fall the perpendiculars _Ba_, _Bb_ on the rectangle sides. Determine the correspondent points _a_ an...
5. Part 5Complete the square, and within it inscribe a circle, as in Fig. 62., which is left unlettered that its construction may be clear. At the extremities of this draw vertical lines...
2. Part 2[6] _P_ and _Q_ being points indicative of the place of the tower’s base and top. In this figure both are above the sight-line; if the tower were below the spectator both would...
6. Part 6It will be seen that the construction given in the text (Fig. 46.) is the simplest means of obtaining this magnitude, for _VD_ in Fig. 46. (or _VM_ in Fig. 15.) = _VT_ by constr...
