Geometry = Shapes

by Bill Lauritzen

Plane Geometry = Flats

Solid Geometry = Shapes

 

plane figure

flat

1

3-D figure or spacial figure

4

shape

1

perimeter

4

around or border or fence

2

area

3

skin or fill 

1

volume

2

 fill

1

 

Thus:

length of a line

skin of a flat

fill of a shape

 

Old: The area of a rectangle is length times width. To find the perimeter of a rectangle add the lengths of all the sides. The volume of a cube is length time width times height.
New: The skin of a rectangle is length times width. To fence a rectangle add the lengths of all the sides. The fill of a cube is length times width times height.

The Chinese use "straight-line" and "half-line" for diameter and radius.
ring = fat-ring


Old: The circumference of any circle divided by the diameter of the circle is the same: 3.14, or pi. A circle has 360 degrees. The volume of a cylinder equals pi times the radius squared times the height.
New: The around of any ring divided by the across of the ring is the same: 3.14, or pi. A ring has 360 twiks. The fill of a can evens pi times the spoke two’d times the height.

Old: Triangles are the only stable polygon. If one puts string through drinking straws, this is easy to demonstrate. A quadrilateral, hexagon, decagon, icosagon, in fact all other polyhedra, will collapse, while the triangle keeps its shape.
New: Three-niks are the only stable many-niks. If one puts string through drinking straws, this is easy to demonstrate. A 4-nik, 6-nik, 10-nik, 20-nik, in fact all other many-niks, will collapse, while the 3-nik keeps its shape.

Nook is used because it is another name for a corner and the number of corners can identify the five elemental polyhedra.

 

Old: A tetrahedron has 4 vertices, 6 edges, and 4 sides.
New: A 4-nook has 4 nooks, 6 lips, and 4 flats.

Old: Sides + vertices – edges = 2

New: Flats + nooks – lips = 2

 

simplest flat figure = simplat = three-nik

simplest spacial shape = simplex = four-nook

[The two bases of the shape match and track.]

5

cubic-6-nook

4

truncated tetrahedron

7

cut-off-4-nook

4

pentagonal prism

6

 5-nik prism

4

 

Old: There are only five regular polyhedra. Because they are made of triangles, tetrahedrons, octahedrons, and icosahedron are stable. Hexahedrons and dodecahedrons are not.
New: There are only 5 even many-nooks. Because they are made of 3-niks, 4-nooks, 6-nooks, and 20-nooks are stable. 8-nooks and 12-nooks are not.

4

 

Old: The measures of the angles of a triangle always add up to 180 degrees. In an equilateral triangle, all the sides and angles are equal.
New: The measure of the niks of a 3-nik always adds up to 180 twiks. In an even 3-nik, all the sides and niks match.

New: A right 3-nik has two legs and a shlong.

3

zoom or zoomy

1

 

["Similar triangles" can be called "zoom triangles" or "zoomies" because of the widespread use of the zoom lens, which was unknown to the ancients. Of course, one may have to flip and/or spin the triangle to see the "zoomability." Zoom here does refer to an actual increase in size not an illusory increase in size as in a lens.]

* The two angles fill a right angle.

Old: An acute angle is less than 90 degrees. An angle and its complement add up to 90 degrees.
New: A sharp nik is less than 90 twiks. A nik and its right-fill add to 90 twiks.

New: If two along lines are crossed, then each pair of same-side in-niks straight-fill.
Old: If two parallel lines are crossed by a transversal, then each pair of alternate exterior angles are congruent.
New: If two along lines are crossed, then each pair of other-side out-niks match.
