Página 64 - It may be necessary here to remark, that though the upper part of the section intersects the cone at a much less diameter in its length than at the lower part of the section, nevertheless each half of ths ellipse from the middle of its length is identical.
Página 49 - Any multiples of these numbers may be used with equal propriety, when convenient ; as 6, 8, and 10, or 9, 12, and 15, whether inches, feet, or any other units of length. To draw a perpendicular to a given line from a given point without the line. FIRST, When the point is conveniently near the middle of the line. 1.
Página 241 - Or, use a straight edge and triangle. Or, use a sheet of celluloid with a set of lines parallel to one edge and about И in.
Página 51 - This is the line required. The methods of describing squares and rectangles already given are also available for drawing parallels ; though they are not so generally ready of application as the foregoing. To divide a straight line into any number of equal parts. 1. Let AB, Fig. 108, be the straight line, to be divided — c i D -- Fig.
Página 50 - If there be no room below the line AB the intersections F may be taken above, that is between the point c and the line. This mode is not, however, so good as the one already described, because it is not likely to be so exact.
Página 35 - Fig. 28. the lines have nothing to do with the size of the angle : thus, these two angles (Figs. 27 and 28) are said to be equal. If the lines are both straight, it is called a rectilineal angle ; if both curved, a curvilineal angle. The lines are the sides of the angle ; the point of meeting is the vertex of the angle. Right Angle. — When one straight line stands upon another, so as to make the two angles equal, each of these angles is called a right angle (Fig. 29) ; and one line is said to be...
Página 52 - E the .s line upon which an equal angle is to be drawn at the point D. From the points A and D, with any convenient radius, describe arcs FG and H i. 2. Set off the length of the arc FG, contained between the lines AB and A c, upon the arc H i, and draw D i.
Página 52 - The latter will thus be divided into five equal parts. To construct an equilateral triangle. 1. Let AB, Fig. 110, be the length of the side of the triangle. On A and B as centres, with radius AB describe arcs cutting each other at c. 2. Join AC and EC; the triangle, ABC, Kg.
Página 53 - III. 16). 2d. Let C be the given angle. With C as a centre describe an arc cutting the sides of the angle in A and B ; bisect the arc AB with the line CD, and it will also bisect the angle C (III.
