I'm trying to measure the length, width, and height of a fold of mine. It
basically has the shape of prism with a kite base. The thing is I'm
confused about which two points correspond to length and which two
correspond to width.
Dear Gerardo:
The base of your prism is a convex deltoid or kite.
The best way to describe a kite is to give the length of both
diagonals (minor and major).
Length and width are appropriate parameters to fully describe a
rectangle, but not a kite.
Should the base be an ellipse, you would have to give the length of
both diameters, and if it were a circle, the radius or the diameter.
Hope this helps.
