    QUESTION ONE

    1. Using a word processing program reproduce the work below and save the document as Geometry One       [32 Marks]

    History of Geometry

    Egyptians c. 2000 – 500 B.C.

    A

    ncient Egyptians demonstrated a practical knowledge of geometry through surveying and construction projects. The Nile River overflowed its banks every year, and the river banks would have to be re-surveyed. See a PBS Nova unit on those big pointy buildings. In the Rhind Papyrus, pi is approximated.

     

    Babylonians c. 2000 – 500 B.C.

    Ancient clay tablets reveal that the Babylonians knew the Pythagorean relationships. One clay tablet reads“4 is the length and 5 the diagonal. What is the breadth? Its size is not known. 4 times 4 is 16. 5 times 5 is 25. You take 16 from 25 and there remains 9. What times shall I take in order to get 9? 3 times 3 is 9. 3 is the breadth”.

     

    Greeks c. 750-250 B.C.

    Ancient Greeks practiced centuries of experimental geometry like Egypt and Babylonia had, and they absorbed the experimental geometry of both of those cultures. Then they created the first formal mathematics of any kind by organizing geometry with rules of logic. Euclid’s (400BC) important geometry book The Elements formed the basis for most of the geometry studied in schools ever since.

     

    The Fifth Postulate Controversy c. 400 B.C. – 1800 A. D.

     

    There are two main types of mathematical (including geometric) rules: postulates (also called axioms), and theorems.Postulates are basic assumptions – rules that seem to be obvious and are therefore accepted without proof. Theorems are rules that must be proved.

    Euclid gave five postulates. The fifth postulate reads: Given a line and a point not on the line, it is possible to draw exactly one line through the given point parallel to the line.

     

     

    Geometry Today

    Today geometry has a wide range of applications. Amongst the applications it is used for includes: Building and construction, Mechanical plant engineering, Art and design. For example, the drawings below have been reproduced using geometry.
