12 orthogons---part 1:review of the drawing method

I study 12 orthogons by chance and read wiki times to understand these drawing method. And I had found that there might be some mistake to explain the ratio for some of them.

I checked at internet and found one web which published the all 12 orthogons . It showed that my concern is correct. But the drawing method had a little mistake even the ration is correct. So I decided to redraw all these 12 orthogons. Most method is same except the Penton.

I will post the reason in following articles .
