Here each face of the octahedron is replaced by six scalene triangles, so that altogether there are 575 forty-eight faces.
A scalene triangle abc might also be employed, or a tetrahedron.
Now of the two triangles, the isosceles has one form only; the scalene or unequal-sided has an infinite number.
The points we occupied respectively formed a scalene triangle.
Of triangles there are two kinds; one having the opposite sides equal (isosceles), the other with unequal sides (scalene).
On the other hand, triangles can be divided into equilateral, isosceles and scalene, since no other kind of triangle can exist.
But it is sometime rationall, and to be expressed by a number: yet but in a scalene triangle onely.
The dramatis persona in their relative positions first formed an isosceles triangle, then a scalene, afterwards a right line.
The general form is bounded by twelve scalene triangles and is a ditrigonal bipyramid.
The first solid is a regular pyramid, of which the base and sides are formed by four equilateral or twenty-four scalene triangles.
"having unequal sides," 1680s, from Late Latin scalenus, from Greek skalenos "uneven, unequal, odd (numbered)," as a noun, "triangle with unequal sides," from skallein "chop, hoe," from PIE *(s)kel- (1) "to cut" (see scale (n.1)).
