Transcript of Geomerty
The earliest recorded beginnings of geometry can be traced to ancient Mesopotamia and Egypt in the 2nd millennium BC. Early geometry was a collection of empirically discovered principles concerning lengths, angles, areas, and volumes, which were developed to meet some practical need in surveying, construction, astronomy, and various crafts.The earliest known texts on geometry are the Egyptian Rhind Papyrus (2000–1800 BC) and Moscow Papyrus (c. 1890 BC), the Babylonian clay tablets such as Plimpton 322 (1900 BC). For example, the Moscow Papyrus gives a formula for calculating the volume of a truncated pyramid, or frustum.
History Of Geometry
The theme of symmetry in geometry is nearly as old as the science of geometry
itself. Symmetric shapes such as the circle, regular polygons and platonic solids
held deep significance for many ancient philosophers and were investigated in
detail before the time of Euclid. Symmetric patterns occur in nature and were
artistically rendered in a multitude of forms, including the graphics of M. C. Escher.
Nonetheless, it was not until the second half of 19th century that the unifying
role of symmetry in foundations of geometry was recognized. Felix Klein's
Erlangen program proclaimed that, in a very precise sense, symmetry, expressed
via the notion of a transformation group, determines what geometry is.
Symmetry in classical Euclidean geometry is represented by congruences and
rigid motions, whereas in projective geometry an analogous role is played by
collineations, geometric transformations that take straight lines into straight lines.
Symmetry
Geometry is a branch
of mathematics concerned with questions of
shape, size, relative position of figures, and the
properties of space.
A mathematician who works in the field of
geometry is called a geometer.
