Chapter 2 Vocabulary - Discovering Geometry

Inductive reasoning

• process of showing that certain statements follow logically from agreed-upon assumptions
• a line intersecting two or more other lines
• the process of observing data, recognizing patterns, and making generalizations about those patters (trial and error)
• a convincing argument that uses deductive reasoning.

conjecture

• A generalization resulting from inductive reasoning.
• A pair of angles formed by a transversal intersecting two lines that lie between the two lines and are on the same side of the transversal.
• A convention for expressing a function rule in terms of its input.
• A rule that, when applied to one set of numbers, generates another set of numbers with at most one output value for each input value.

postulate

• a statement accepted without proof, because it cannot be disproved.
• Two angles formed by a transversal intersecting two lines that lie in the same position relative to the two lines and the transversal.
• A function that has a constant difference between consecutive terms.
• A rule that, when applied to one set of numbers, generates another set of numbers with at most one output value for each input value.
