Side 50 - In any triangle, the sides are proportional to the sines of the opposite angles, ie. t abc sin A sin B sin C...
Side 25 - Similar figures, are those that have all the angles of the one equal to all the angles of the other, each to each, and the sides about the equal angles proportional.
Side 326 - Solids which decrease gradually from the base till they come to a point, are generally called Pyramids. If the base be a square, it is called a square pyramid; if a triangle, a triangular pyramid ; if a circle, a circular pyramid, or a cone.
Side 213 - ... meridians were drawn parallel to each other, and, confequently, the parallels of latitude made equal to the equator, and fo a degree of longitude on any parallel, as large as a degree on the equator: alfo, in thefe charts, the degrees of latitude were ftill reprefented (as they are in themfelves) equal to each other, and to thofe of the equator; by thefe means the degrees of longitude being increafed beyond their juft proportion, and the more fo 'the nearer they...
