...circumference is an arc. 333. The circumference of a circle is divided into 360 equal arcs, called A clrcle degrees (°), each degree into 60 minutes ('), and each minute into 60 seconds ("). These are the units of Circular Measure. 60 seconds = 1 minute. 60 minutes = 1 degree. 360 degrees...

...at each of the legs, the first in the middle (£ BAG). 12. A whole revolution is divided into 360° (degrees), each degree into 60' (minutes), and each minute into 60" (seconds); an angle of 180°, corresponding to half a revolution, is called an angle of continuation ; its legs...

...at each of the legs, the first in the middle (Z. BAC). 12. A whole revolution is divided into 360° (degrees), each degree into 60' (minutes), and each minute into 60" (seconds); an angle of 180°, corresponding to half a revolution, is called an angle of continuation; its legs...

...Secondly, as to direction. If we conceive any circle to be divided into 360 equal parts or measures (called degrees), each degree into 60 minutes, and each minute into 60 seconds ; then, since, as Euclid demonstrates (VI. 33), the number of such parts in any given arc will be independent...

...purpose of determining the exact position of a place on the globe. All circles are divided into 360 degrees, each degree into 60 minutes, and each minute into 60 seconds. The whole distance from the equator to either pole is 90°. These parallels divide this distance into...

...them in the ratio of their respective earnings. 20. In the English system a circle is divided into 360 degrees, each degree into 60 minutes, and each minute into 60 seconds. In the French system each circle is divided into 4 quadrants, each quadrant into 100 grades, each grade...

...angular measurement is the circle and its various divisions. A circle is divided into 860 equal parts or degrees, each degree into 60 minutes, and each minute into 60 seconds. The ANGLE A Fig. 143. Fig. 144. Fig. 145. following symbols are used to denote these divisions and...

...had not known that the earth was a sphere. Again, we have derived our division of a circle into 360 degrees, each degree into 60 minutes, and each minute into 60 seconds, from the Greeks, and they received it from the Babylonians. Hence we see that the fundamental principles...

...of arc. • ii Circumference of every circle is supposed to be divided into 360 equal parts, termed Degrees ; each degree into 60 Minutes, and each minute into 60 Seconds, and so on. Complement of an angle is what remains after subtracting angle from go degrees. Supplement...

...: degrees (°), minutes ('), and seconds (") ; the circumference of a circle being divided into 360 degrees, each degree into 60 minutes, and each minute into 60 seconds. Thus, the Great Bear's tail, 1 This is the same as the ' vanishing-point ' of perspective. or Dipper-handle,...
