Can any one recommend what package I should use? and some ideas to do it? I reall have no idea.

Thank you in advance.

Here the first 5 pictures obtained using tkz-euclide and tikz. Then you can arrange the pictures in yours order and enviroment.

Remove comment % to look at points coordinates.

\documentclass{scrartcl}
\usepackage{tikz}
\usepackage{tikz-cd}
\usetikzlibrary{decorations.markings}
\usetikzlibrary{angles}
\usepackage{tkz-euclide}
\usetkzobj{all}     

\begin{document}
\tikzset{->-/.style={decoration={
  markings,
  mark=at position #1 with {\arrow{>}}},postaction={decorate}}}
\tikzset{->>-/.style={decoration={
  markings,
  mark=at position #1 with {\arrow{>>}}},postaction={decorate}}}
