Isosceles :: Isosceles (a.) Having two legs or sides that are equal; -- said of a triangle.

Base :: Base (n.) A line in a survey which, being accurately determined in length and position, serves as the origin from which to compute the distances and positions of any points or objects connected with it by a system of triangles..

Pyramid :: Pyramid (n.) A solid figure contained by a plane rectilineal figure as base and several triangles which have a common vertex and whose bases are sides of the base.

Triangle :: Triangle (n.) A figure bounded by three lines, and containing three angles..

Three-square :: Three-square (a.) Having a cross section in the form of an equilateral triangle; -- said especially of a kind of file.

Acute-angled :: Acute-angled (a.) Having acute angles; as, an acute-angled triangle, a triangle with every one of its angles less than a right angle..

Scalene :: Scalene (n.) A triangle having its sides and angles unequal.

Amblygon :: Amblygon (n.) An obtuse-angled figure, esp. and obtuse-angled triangle..

Spherograph :: Spherograph (n.) An instrument for facilitating the practical use of spherics in navigation and astronomy, being constructed of two cardboards containing various circles, and turning upon each other in such a manner that any possible spherical triangle may be readily found, and the measures of the parts read off by inspection..

Trilateral :: Trilateral (a.) Having three sides; being three-sided; as, a trilateral triangle..

Revolution :: Revolution (n.) The motion of a point, line, or surface about a point or line as its center or axis, in such a manner that a moving point generates a curve, a moving line a surface (called a surface of revolution), and a moving surface a solid (called a solid of revolution); as, the revolution of a right-angled triangle about one of its sides generates a cone; the revolution of a semicircle about the diameter generates a sphere..
