An angle formed by the intersection of two great circles of a sphere.
‘For a spherical angle of 180°, the lune becomes half of a sphere or a hemisphere.’
‘The coordinates in the projection of an arbitrary triangle are determined by the ratios between spherical angles.’
‘Here's the code to convert mouse coordinates to spherical angles.’
‘With a protractor and a little practise it is possible to measure spherical angles pretty accurately.’
‘In this paper we formulate a set of necessary and sufficient conditions on the spherical angles of the spherical triangles for them to form a spherical triangulation.’
‘The local hour angle is the spherical angle between the observer's meridian and the body's meridian, drawn here at the elevated pole.’
‘It is common practice to record the light intensity at a large number of spherical angles from a specific luminaire (photometric data set) onto magnetic media, such as a computer disk.’
‘The table below shows how much or little the spherical angles between planets are in my horoscope.’
‘The epoch of the coordinates represents the date to which the spherical angles are reduced.’
‘The angle between two lines corresponds to the spherical angles of the corresponding great circles.’
‘A system adapted for coupling to an optical conduit provides an input or output port for the transmission of radiant energy to or from the conduit over a spherical angle greater than a hemisphere.’
‘We then define solid angles, 1 and 2, in terms of the plane angle components in exact analogy to spherical angles defined in terms of line components.’
