  • A spherical triangle is subtended by a polyhedral angle whose vertex is the centre of the sphere.
  • The sum of the degree measures of the interior angles of a spherical triangle ranges from 180° to 540°.
  • A spherical triangle can be a right spherical triangle, which helps to conceptualize spherical trigonometry.
