- (diff | hist) . . Geometry/Chapter 1; 02:46 . . (+219) . . Sluffs (discuss | contribs) (→Vocabulary: adding some info on the summation sign - why the "n" is at the top and the "x =1" is at the bottom)

**(+755)** . . Sluffs (discuss | contribs) (just adding Euclid's Common Notions on Equality - from the Richard Fitzpatrick book (six lines) - this is simply to show that the deductive example is an equation) - (diff | hist) . . m Geometry/Chapter 1; 01:53 . . (-4) . . Sluffs (discuss | contribs) (→Section 1.2 - Reasoning: removed italics)
- (diff | hist) . . Geometry/Chapter 1; 01:52 . . (-160) . . Sluffs (discuss | contribs) (removedː "==Objective== Students demonstrate understanding by identifying and giving examples of undefined terms, axioms, theorems, and inductive and deductive reasoning." - Reasonː not needed - no objectives = no pressure = quicker learning)
