| 100% | CAKE = TOO REAL PIE! | Circumference (Around Kitchen Edible) = Two (One + One) * Radius * (Eating Always Luscious) Pi (Irrational Escape!) | Charles H. Montgomery, Jr. Boston Cream Cake: Also (Too) Pie! Food & Drink | 
| 100% | CIRCLE | Calculation Into Route Consistently Locus-Equidistant | Tony McCoy O'Grady | 
| 100% | CIRCLE (2) | Circulating, Inhabitable, Rotational, Cycle Logical Ellipses/Eclipses! | Charles H. Montgomery, Jr. CIRCLE!  EARTH: DAYS, YEARS, Eclipses & the wonderful Cycle Logical PREDICTABLE SCIENCE. | 
| 100% | CIRCLE PERIMETER | Circumference (Irrational Ratio Called-Logically!) Equals Pi! (Energizes Representation In Math Equations) Two (Er) Radius | Charles H. Montgomery, Jr. Outside of parentheses in EXPANSION: Circumference = Pi Two Radiusor C=2*Pi*R. The ! signals that (Irrational Ratio Called-Logically!) is Pi! "Called-Logically!" is a PUNNY way of saying "most Pies are CIRCLES." Er is Chinese Two. Hope the grave accent for Èr worked. I thought that (Energizes Representation In Math Equations) was very important. For centuries, primary school children have learned C=2*Pi*R, so this inclusion might help whoever reads this APRONYM when they study advanced math. | 
| 100% | CUBE | Completely Unirregular Blocky Entity | Tony McCoy O'Grady | 
| 100% | CYLINDER | Circular Yet Long, It Neatly Drains Excess Rainwater. | Angela Brett | 
| 86% | FIGURE | Fanciful Ideas in Geometry, Usually Rectilinear Equilaterals | Angela Brett | 
| 100% | GEOMETRY | Golly, Elementary Orthogonal Matrices Excite These Randy Youths. | Angela Brett, during a boring first-year algebra lecture. Education:Slow Teaching | 
| 100% | GEOMETRY (2) | Go Euclid! One Man's Elementary Text Remained Years! | Angela Brett (parts of Euclid's 'Elements' were used as a standard textbook for around 2250 years.) | 
| 100% | GEOMETRY (3) | Greek Earth Observers Measured Everything, Trusting Real Yardsticks. | Angela Brett, since geometry began with people actually measuring land and wasn't at all like the abstract science it is today. | 
| 100% | ISOMETRIES | Images Simulate Originals, Mostly. Examples: Translations, Rotations Imitate Exact Shape | Angela Brett. (An isometry is a plane transformation which preserves distances, and therefore shapes of figures.) | 
| 77% | ISOMETRIES (2) | Imitate Shapes of Originals, at Most Expressible as Three Reflections In Every Situation | Angela Brett. (Every isometry can be expressed as a product of at most three reflections.) | 
| 93% | JUXTAPOSITION | Juggle Until X-axes Tally, Although Placing Objects Spatially In Togetherness Is Often Noisome. | Tony McCoy O'Grady | 
| 100% | ORB | One Round Ball | Angela Brett | 
| 100% | PARALLEL LINES | Partings Are Rigidly Applied, Logical Legalities Exclude Lines Lurching Into Nexus - Eternally Separated | Tony McCoy O'Grady, who always wondered why concentric circles do not qualify as 'parallel'. | 
| 91% | QUADRATRIX | Quite Useful in Answering Dilemma... Round's Area To Rectangle Impossibility Xamined. | Angela Brett | 
| 100% | RADIUS | Rip A Diameter Into Uniform Sections | Angela Brett | 
| 100% | SHAPE | Solidity Has A Physical Embodiment | Tony McCoy O'Grady | 
| 100% | SPHERE | Solid Paradigm Having Every Radius Equal | Angela Brett | 
| 100% | SQUARE | Shape Quadrilateral, Unvaryingly A Rightangled Equilateral | Tony McCoy O'Grady | 
| 100% | SQUARES | Some Quadrangles Use Angles Right; Even Sides. | Roger Williams | 
| 100% | TRIANGULAR | This Really Is A Nice Geometric Unit... Lines Are Reduced. | Angela Brett | 
| 100% | TROCHOID | Tracing Rolling Of Circle Has One Immediately Dizzy! | Angela Brett |
