3.3.40 Line and plane in space
condition: Find a point symmetrical to a given point \(A\) relative to a line passing through a given point \(B\) and perpendicular to a given plane. \[ A(18,20,15), \quad B(7,9,4), \quad x-y+3 z-8=0 \text {. } \]
Straight lines and planes in space. Intersection of lines and planes, calculation of the distance of a line and a plane, angles between lines and planes, finding equations of lines and planes in space, and much more.
