If the generalization is true and the reasoning is valid, the specific statement will always be true.  Inductive and deductive reasoning is used in developing patterns both algebraically and geometrically.</p><p>Essential Questions  How do inductive and deductive reasoning differ?  What special relationships occur between pairs of angles when parallel lines are cut by a transversal?  How can algebra be used to show geometric relationships?</p><p>Academic Concepts  slope  perpendicular  converse  transversal  constructions bisector  reasoning  same side interior  midpoint formula  bi-conditional  parallel lines angles  distance formula  conditional statement perpendicular lines  congruent  complementary  converse  corresponding segments  supplementary  informal proof angles  adjacent angles  angle bisector  counterexample  vertical angles  congruent angles  spherical geometry  deductive  alternate interior reasoning angles</p><p>Performance Descriptor  Use logical reasoning to determine if statements are true or false and give a counterexample.  Write a statement in if-ten form and write its converse, inverse, and/or contra-positive.  Explore the relationships between pairs of angles and parallel or perpendicular lines.  Use coordinate points to determine measures of length, including midpoint and distance. </p>
