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...
Side 113 - ... Sunday of January, in a common year, will show all the Sundays throughout the year, and to whatever days in the rest of the months, that letter is put, these days are all Sundays. If the first day of January be on a Sunday, the next year will begin on Monday, and the Sunday will fall on the seventh day, to which is annexed the letter G, which therefore will be the Sunday letter for that year; the next year beginning on Tuesday, the first Sunday will fall on the sixth of January, to which is adjoined...
