Geometry Unit 2

Geometry Basic Reasoning and Figures

10 Instructional Days - 1st 6 Weeks

Hyperlinks are for content teachers

Big Idea:

Use Inductive and Deductive reasoning to analyze conjectures.

Student Expectations:

Priority TEKS

G.4(B) [Supporting] identify and determine the validity of the converse, inverse, and contrapositive of a conditional statement and recognize the connection between a biconditional statement and a true conditional statement with a true converse

Focus TEKS

G.4(A) [Supporting] distinguish between undefined terms, definitions, postulates, conjectures, and theorems

G.4(C) [Readiness] verify that a conjecture is false using a counterexample

Student Learning Targets:

  • I will make conjectures by applying inductive reasoning.
  • I will use Deductive reasoning to analyze a conjecture
  • I will develop geometric and algebraic arguments based on deductive reasoning.
  • I will identify the hypothesis and conclusion of the conditional statement.
  • I will give counterexamples for the false conditional statements.
  • I will write and determine the truth value of the converse, inverse, and counterexample of a conditional statement.
  • I will write and interpret bi-conditional statements.

Essential Questions:

  • What makes a valid system of mathematics and why is it important?
  • How are valid Logical arguments constructed?
  • Why is making logical arguments an important skill for everyone?
