Σελίδα 28 - If two triangles have two sides of the one equal to two sides of the...
Σελίδα 12 - Any two sides of a spherical triangle are together greater than the third side.
Σελίδα 19 - Thus the sines of the angles of a spherical triangle are proportional to the sines of the opposite sides.
Σελίδα 30 - From this proposition, it is obvious that if one angle of a triangle be equal to the sum of the other two angles, that angle is a right angle, as is shewn in Euc.
Σελίδα 1 - A sphere is a solid bounded by a surface, every point of which is equally distant from a fixed point called the centre.
Σελίδα 62 - A circle which touches one side of a triangle and the other two sides produced, is called an escribed circle of the triangle.
