...60 equal parts, called minutes; and so on. 48. The measure of any right-lined angle is an arc of a circle contained between the two lines which form that angle, the angular point being the centre. Note. The angle is estimated by the number of degrees contained in the arc; whence a right angle is... | |

...measure of a right-lined angle is the arc of any circle contained between the two lines which form the angle, the angular point being the centre, and it is estimated by the number of degrees in that arc. (Plate 3, fig. 19.) A right-lined figure is inscribed in a circle when all the angular... | |
