Postulates and Theorems to be Examined in Spherical Geometry Some basic definitions: 1. Line segment: The segment AB, AB, consists of the points A and B and all the points on line AB that are between A and B. 2. Circle: The set of all points, P, in a plane that are a fixed distance from a fixed point, O, on that plane, called the center of the File Size: KB. A Square is a flat shape with 4 equal sides and every angle is a right angle (90°) Opposite sides are parallel (so it is a Parallelogram). A square also fits the definition of a rectangle (all angles are 90°), a rhombus (all sides are equal length), a parallelogram (opposite sides parallel and equal in length) and a regular polygon (all.

Spherical triangles were studied by early Greek mathematicians such as Menelaus of Alexandria, who wrote a book on spherical triangles called Sphaerica and developed Menelaus' theorem.  E. S. Kennedy, however, points out that while it was possible in ancient mathematics to compute the magnitudes of a spherical figure, in principle, by use of the table of chords and Menelaus' . In trigonometry: Passage to Europe. The first definition of a spherical triangle is contained in Book 1 of the Sphaerica, a three-book treatise by Menelaus of Alexandria (c. ce) in which Menelaus developed the spherical equivalents of Euclid’s propositions for planar triangles.A spherical triangle was understood to mean a figure formed on the.

A triangle in spherical geometry is formed by the intersection of three arcs that lie on different great circles. Recall that the proof of the Triangle Angle-Sum Theorem in Euclidean geometry uses the Euclidean Parallel Postulate, which does not hold in spherical geometry. So the Euclidean Triangle Angle-Sum Theorem is invalid in spherical. Plane geometry deals with points, lines, polygons (A shape with more than two sides, i.e. square, triangle, hexagon, etc.) and circles on a flat surface (plane). Sheet metal flat patterns are done in plane geometry.

Two practical applications of the principles of spherical geometry are navigation and astronomy. In plane (Euclidean) geometry, the basic concepts are points and (straight) a sphere, points are defined in the usual sense.

Elements of Plane Trigonometry. First Chapter explains Newton's Method of Limits to the mensuration of circular arcs and areas.

The succeeding Chapters are devoted to an exposition of the nature of the Trigonometrical ratios, and to the demonstration by geometrical constructions of the principal propositions required for the Solution of Triangles.

The Circle. The circle is a shape that can be made by tracing a curve that is always the same distance from a point that we call the center.

The distance around a circle is called the circumference of the circle. A practical text-book on plane and spherical trigonometry.

By the File Size: KB. In spherical geometry, a square is a polygon whose edges are great circle arcs of equal distance, which meet at equal angles. Unlike the square of plane geometry, the angles of such a square are larger than a right angle.

Larger spherical squares have larger angles. In hyperbolic geometry, squares with right angles do not exist. Rather, squares Symmetry group: Dihedral (D₄), order 2×4.

\$\begingroup\$ +1 This looks like an awesome resource and an interesting read. I've ordered a copy. Thanks. I'm still hoping to find something that focuses more exclusively on the development of spherical geometry--less interlaced with the corresponding planar story and including more information about non-trigonometric approaches and facts about the geometry of the sphere.
