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.
