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.
