Thales of Mileus (contd.)

Geometry originated from Africa. Though the two words that form Geometry are of Greek origin. They ‘geo’ and ‘metrein’. ‘Geo’ means earth and ‘metrein’ means to measure. Literally Geometry means earths’ measurement.

It was being used by the ancient Greek ‘hapenodapta’ which can be described as nowadays Surveyors after the yearly Nile’s flood to remark lands for farming.

Geometry to ancient Egyptians was at descriptive stage. However, the Greeks introduced the rational methods that gave ‘Geometry’ its aesthetic beauty into it.

Thales of Miletus mentioned two days ago is credited with the theorems listed below:

       i.            A circle is bisected by any diameter.

     ii.            The base angles of an isosceles triangle are equal.

  iii.            The angles between two intersecting straight lines are equal.

   iv.            Two triangles are congruent if they have two angles and one side equal.

     v.            An angle in a semicircle is a right angle.

We shall discuss more on this theorems and geometry per se as the day goes by. Keep checking the blog.
