Coplanar

Structures of the twelve dioxin-like PCBs ;Coplanar or non-ortho The coplanar group members have a fairly rigid structure, with their two phenyl rings in the same plane.

Also, an orthogonal line through T to a chosen face is coplanar with two other orthogonal lines to the same face.

If these square pyramids are then attached to the faces of a second cube, a rhombic dodecahedron is obtained (with pairs of coplanar triangles combined into rhombic faces).

It also refers to the plane of this path, which is coplanar with the orbit of Earth around the Sun (and hence the apparent orbit of the Sun around Earth).

Others can be obtained by joining cubes together, although care must be taken if coplanar faces are to be avoided.

Single and multiple planets could be captured into arbitrary unaligned orbits, non-coplanar with each other or with the stellar host spin, or pre-existing planetary system.

The coplanar PCBs, known as nonortho PCBs because they are not substituted at the ring positions ortho to (next to) the other ring, (i.e. PCBs 77, 126, 169, etc.), tend to have dioxin -like properties, and generally are among the most toxic congeners.
