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.

Etymology: L. triangulum, fr. triangulus triangular; tri-see Tri-) + angulus angle: cf. F. triangle. See Angle a corner
