A parallelepiped (in other words: a paralleogram based oblique prism)* ABCDA*_{x}*B*_{x}*C*_{x}*D*_{x }is given by the vertices A, B and D of the base ABCD, moreover the endpoint *A*_{x} of the lateral edge *AA*_{x}. Construct its imeges. Divide each edge of the parallelepiped into three segments in ratio 1 **:**
√2 **:** 1. The construction of dividing points can be seen in the figure below. Truncate each vertex of the parallelepiped
by the plane that goes through the first dividing points of edges
emanating from the vertex. Construct the images of truncated parallelepiped and show the visibility. *A*(70, 100, 165); *B*(90, 40, 195); *D*(130, 130,
185); *A*_{x}(40, 120, 225).
