Drawing parallels

Data :

• a straight line (AB) ;

• a point P outside the line (AB).

1. Solution 1

   Layout :

   • From point P, draw a circular arc of any radius R ₁ which intersects line (AB) at N ;

   • from point N with the same radius R ₁ , draw a circular arc that passes through point P and intersects the line (AB) at M ;

   • transfer the length of arc PM (R ₂ ) to an arc of center N that intersects...
