Geometrical Model by A. Harry Wheeler, Oblique Spherical Triangle

<< >>
Description
This small plastic model is of a scalene oblique spherical triangle. It consists of three discs of a sphere with a common center, whose straight edges are glued together to form the spherical triangle. None of the angles between the discs is a right angle (hence the triangle is oblique) and the three angles are unequal (hence the triangle is scalene).
Models MA*304723.707 and MA*304723.710 are mirror images.
