J is the piercing point
1
The point J is the point of intersection of the plane α
pierced by the straight line d, what can be marked as;
J = αd.
Problem 12. Define a line n that includes
the given point P and is perpendicular to
the given plane γ determined by the point
M and the straight line f. Where is the
piercing point J (common element
between the plane γ and line n)?
Problem 13. Define two straight
lines m and f, that both include
the given point A, and both are
skew lines with respect to the
given horizontal line p, and are
perpendicular to that line.
Define the set of such lines.
