Stereoisomeric olefins, cycloalkanes, etc. which differ in the positions of groups relative to a reference plane: in the cis-isomer the atoms are on the same side, in the trans-isomer they are on opposite sides. An obsolete synonym, for which the usage is strongly discouraged, is geometric isomerism.

Physical properties of geometric isomers
In the case of fumaric acid, intermolecular hydrogen bonds are the reason beyond its higher melting point compared with the melting point of maleic acid ( where intramolecular hydrogen bonds dominate) …

Why are oxime geometrical isomers stable?
It's a matter of energetic barrier between the $E$ and $Z$ stereoismers. It's sufficiently low for imines. So, it's relatively difficult to isolate $E$ or $Z$ stereoismer.
In the case of oximes, the …

Stability of cis vs trans isomers?
Contrary to the generally accepted belief, many cis isomers of olefinic compounds are more stable than their trans isomers. The stable cis form of substituted olefins such is 1–fluoro–1, 3–butadiene …
