three angles.
[1913 Webster]
Note: A triangle is either plane, spherical, or curvilinear,
according as its sides are straight lines, or arcs of
great circles of a sphere, or any curved lines
whatever. A plane triangle is designated as scalene,
isosceles, or equilateral, according as it has no two
sides equal, two sides equal, or all sides equal; and
also as right-angled, or oblique-angled, according as
it has one right angle, or none; and oblique-angled
triangle is either acute-angled, or obtuse-angled,
according as all the angles are acute, or one of them
obtuse. The terms scalene, isosceles, equilateral,
right-angled, acute-angled, and obtuse-angled, are
applied to spherical triangles in the same sense as to
plane triangles.
