EDGE is a line. ... 2D
---------------------------------
2D: head ~ ellipse.
3D: head ~ elliptoid.
Half head ~ hemieliptoid.
Ear ~ elliptoid.
--------------------------------
All Shapes ~ Continuous -> Equation
Simplify to ~ Deiscrete -> matrix
Piece each matrix together:
face = hemieliptoid + elliptoid
To answer this question more details need to be provided. For example one a 3D shape one side is called a face.
A sphere
a line
You need at least one pair of parallel sides. Most trapezoids have that.
A cone has only one face and laid flat it would look like a piece/slice of cake
A moebus strip.
A place where two faces meet is called an edge.
prism
You would call the group of shapes which has at least one line of symmetry symmetrical shapes. Stars, circles, and rectangles are considered symmetrical shapes.
No, they have only one face.
There are many shapes that have one and only one rectangular face, but an example of one would be a rectangular pyramid.
Assymetrical Balance
Information about different face shapes can be found on many beauty websites, as well as magazines targeted towards females can have information on face shape. Additionally, by going into a beauty salon one would be able to find out much information about face shapes from a beautician.
With no repetition of shapes (symmetry) we have obtained 26 different combinations.
A rhombus is one of them
Assymetrical or Informal balance, they both work.
Pennies have Abraham Lincoln's face on one side. Nickels have Thomas Jefferson on one side. Dimes have Franklin Delano Roosevelt's face on one side. Quarters have Georges Washington's face on them. Half-dollar pieces have John F. Kennedy's face on one side.
