- A shape is a graphical representation of an object’s form or its external boundary, outline, or external surface. It is distinct from other object properties, such as color, texture, or material type. In geometry, shape excludes information about the object’s location, scale, orientation and reflection. A figure is a representation including both shape and size (as in, e.g., figure of the Earth).
- Algenib (stars.astro.illinois.edu)
ALGENIB (Gamma Pegasi). Though the brightest star of Pegasus is Enif, the Epsilon star, the stars of the Great Square are of such obvious note that Bayer gave them Alpha through Delta. Delta (Alpheratz), the brightest, actually belongs to Andromeda as Alpha Andromedae, leaving Alpha, Beta, and Gamma Pegasi (Markab, Scheat, and Algenib) ranking 3-2-4 in the constellation and 2-1-3 in the Square, Algenib the faintest of them.
