Scalene may refer to: A scalene triangle, one in which all sides and angles are not the same. A scalene ellipsoid, one in which the lengths of all three semi-principal axes are different; Scalene muscles of the neck; Scalene tubercle, a slight ridge on the first rib prolonged internally into a tubercle
This means that as physical necklaces on a table the left and right ones can be rotated into their mirror image while remaining on the table. The one in the middle, however, would have to be picked up and turned in three dimensions. A scalene triangle does not have mirror symmetries, and hence is a chiral polytope in 2 dimensions.
Each triangle can be mapped to another triangle of the same color by means of a 3D rotation alone. Triangles of different colors can be mapped to each other with a reflection or inversion in addition to rotations. Disdyakis triacontahedron hulls. The 62 vertices of a disdyakis triacontahedron are given by: [2]
Solution of triangles (Latin: solutio triangulorum) is the main trigonometric problem of finding the characteristics of a triangle (angles and lengths of sides), when some of these are known. The triangle can be located on a plane or on a sphere. Applications requiring triangle solutions include geodesy, astronomy, construction, and navigation.

A tetrahedron is a disphenoid if and only if its circumscribed parallelepiped is right-angled. [9]We also have that a tetrahedron is a disphenoid if and only if the center in the circumscribed sphere and the inscribed sphere coincide.
A double headed arrow joins intersection of lines parallel to sides to the corner of the triangle. This vector forms the two sides of the bottom parallelogram. The blue area is the same as the sum of the green areas, as shown by George Jennings (1997) "Figure 1.32: The generalized Pythagorean theorem" in Modern geometry with applications: with ...
