Side 14 - If a straight line meets two straight lines, so as to make the two interior angles on the same side of it taken together less than two right angles...
Side 8 - The circumference of every circle is supposed to be divided into 360 equal parts, called degrees ; each degree into 60 equal parts, called minutes ; and each minute into 60 equal parts, called seconds.
Side 7 - A circle is a plane figure bounded by a curved line called the circumference, every point of which is equally distant from a point within called the center, Fig.
Side 96 - Any two sides of a triangle are together greater than the third side.
Side 73 - Parallelograms on the same base, and between the same parallels, are equal to one another.
Side 278 - Therefore all the interior angles of the figure, together with four right angles, are equal to twice as many right angles as the figure has sides.
Side 14 - Magnitudes which coincide with one another, that is, which exactly fill the same space, are equal to one another.
Side 266 - A sphere is a solid, bounded by a curved surface, every part of which is equally distant from a point within, called the centre.
Side 45 - From a given point without a line, to draw a perpendicular to that line. Let AB be the given line, and C the given point. From C draw any oblique line, as Cn.
Side 9 - The sign, + , which is read plus, indicates that the numbers between which it is placed are to be added ; thus, 6 + 4, means, that 4 is to be added to 6.
