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 LocusEquidistant 
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 CalledLogically!) 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 CalledLogically!) is Pi! "CalledLogically!" 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 firstyear 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 Xaxes 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!
