Some ideas on the background of Geometry starting with Pythagoras and
seeing geometry in nature can be found in http://www.yale.edu/ynhti/curriculum/units/1984/2/84.02.05.x.html

(and other maths) presentations.
The preliminary
ideas about planes, points and lines are presented interactively at this
teachnet site.
The basic facts
leading to Theorems which are referenced are given at this teachnet
site.
Theorems are statements (sometimes very obvious and sometimes not) which can be
proved absolutely to be true (based on the preliminary ideas and facts which
are allowed). Proving theorems is a major
part of the work of Geometry.
The method of proof is called the method of Deductive Logic
A list of Theorems which are required learning for
the Junior Cert is given at this teachnet site.
At skool.ie a number of lessons in Geometry are
presented.
Geometry
through Art (and the Geometers’ Sketchpad software) is demonstrated on this
site.
