(3) Geometric structure. The student applies logical reasoning to justify and prove mathematical statements. The student is expected to:

  • (A) determine the validity of a conditional statement, its converse, inverse, and contrapositive;
  • (B) construct and justify statements about geometric figures and their properties;
  • (C) use logical reasoning to prove statements are true and find counter examples to disprove statements that are false;
  • (D) use inductive reasoning to formulate a conjecture; and
  • (E) use deductive reasoning to prove a statement.
