Parallel Lines

Steps

1. Construct the perpendicular h to the line p_1.
2. Plot the intersections of the line h with the line p₁ and p₂ and name these points E and F.
3. Construct the axis of the line segment EF and name it S.
4. Determine a random point S_n that lies on the line S. Construct a circle k_n centered at S_n and with radius S_n;p_1.
