Syllabus

1 Thales' Theorem: proof; triangles and sum of internal angles

We found this wonderful property by trying numerous times and here is the place to prove it; the same is true for the sum of the inner angles

  1. Thales' Theorem: proof; triangles and sum of internal angles

2 Special lines and points in triangles, locus lines, Apollonius' circle

In any triangles there are for instance angle bisectors which intersect in one point and this is true for the other 3 special lines too. It's incredible but we can prove it.

  1. Special lines and points in triangles, locus lines, Apollonius' circle

3 Point reflection and rotation as double reflections

Did you ask yourself how double reflections could be proceeded depending on the situation of the 2 axes? Here comes the answer!

  1. Point reflection and rotation as double reflections

4 Congruence of triangles and triangular constructions, gliding ladder

How can we decide whether 2 triangles can be made superposing each other? The 4 cases of Congruence yield the answer - and they allow us to construct triangles with 3 given sides or angles.

  1. Congruence of triangles and triangular constructions, gliding ladder

5 Quadrilaterals: correlations and further constructions

Get to know what types of quadrilaterals exist, how they can be generated from the square with adequate conditions and learn how to construct some of them

  1. Quadrilaterals: correlations and further constructions

6 Area and conversion of quadrilaterals

We are eager to get to know the formulae for the different types of special quadrilaterals and we achieve this goal by converting them to our known rectangle
