Page 104 - A circle is a plane figure contained by one line, which is called the circumference, and is such, that all straight lines drawn from a certain point within the figure to the circumference are equal to one another : 16. And this point is called the centre of the circle.
Page 104 - A diameter of a circle is a straight line drawn through the centre, and terminated both ways by the circumference.
Page 107 - It is like a flattened circle; a plane figure bounded by a curve, every point of which is at the same combined distance from two points within called the foci.
Page 55 - Thus the opening of a right angle is equal to one-fourth of a circle, large or small. and equals ninety degrees, indicated thus, 90°. While the size of a right angle is always the same, the size of an acute or an obtuse angle is always indefinite. If we wish to give the exact size of any angle except a right angle, it must be done in degrees. An acute angle is any angle less than 90°. The angle formed by the lines oe and o l>, being one third of a right angle, is an acute angle of 30° (thirty...
Page 53 - A Square is a surface having four equal sides and four equal angles. A Rectangle is any surface having four sides and four equal angles.
Page 59 - We have dunces enough in this world of ours, beyond all doubt, but the darkest of them all never conceived such a problem as that. Give us the actual evolution of an undeniable effect, and its origin must be explained, — some casual force is necessarily assigned.
Page 55 - From a, as a centre, strike two circles. Draw two straight lines, ab and I d, perpendicular to each other. The two intersecting straight lines, which make four right angles, will divide each circle into four equal parts Thus the opening of a right angle is equal to one-fourth of a circle, large or small. and equals ninety degrees, indicated thus, 90°. While the size of a right angle is always the same, the size of an acute or an obtuse angle is always indefinite. If we wish to give the exact size...
Page 11 - ... step towards success. Consider how we learn to walk, talk, read, write, etc. Be satisfied with little at a time, and keep trying. Let us remember that free-hand drawing is only an approximate description of forms, and is not, like instrumental drawing, a mathematical representation of them. ..." The teacher who has, at the end, nothing to show but finely drawn lines, has given poor instruction. . . . Geometrical accuracy in free-hand drawing is not expected from any one. ... Do not, however,...
Page 219 - A CIRCLE is a figure bounded by a curve line called the circumference,* of which every point is at the same distance from a point within, called the centre. Thus, ABD is a circle, and C the centre. 76. The circumference is divided into 360 equal parts, called degrees, written thus, 360°; each degree, into sixty equal parts, called minutes (6CK) ; each minute into sixty seconds (60") ; and also each second, into sixty thirds (60"'). Example, 11° 19...
Page 104 - It is the longest straight line that can be drawn in a circle, and divides it into two equal parts, called semicircles.
