Conditional Sentence/Congruent Figure/Conjecture/Conjunction
CONDITIONAL SENTENCE (In logically thinking) A sentence of the form “if. . ., then. . .? Example: If 6 x 7 = 42 and 7 x 6 = 42, Then 42 - 6 = 7 and 42 - 6 = 7
CONGRUENT FIGURE Geometric shapes consisting of the same shape and size. Example: 8 x 6 = 48 and 8 x 6 = 48; therefore, 8 x 6 = 6 x 8
CONJECTURE A guess resulting from an experiment. Example: 2, 4, 6, 8, 10 are even numbers; therefore, even numbers must have 0, 2, 4, 5, or 8 in the ones’ place.
CONJUNCTION (In logically thinking) A two-part sentence joined by “and” to form true parts. Example: 1/4 + 1/4 = 2/4 = 1/2
