Unit 3-1 Lines and Angles Agenda
  1. Parallel, Perpendicular, and Skew Lines
  2. Define types of lines & planes (pay attention to symbols)
  3. Angle Pairs Formed by a Transversal
    • Transversal
    • Corresponding Angles
    • Alternate Interior Angles
    • Alternate Exterior Angles
    • Same-Side Interior Angles
  4. Assignment 3-1: Pg. 148 #1-25
Unit 3-2 Angles Formed by Parallel Lines and Transversals Agenda
  1. What is a Conditional Statement?
    • The Hypothesis is the "if" statement
    • The Conclusion is the "then" statement
    • If p is true then q is true or p → q
    • How do we determine if the statement is true or false?
  2. Related Conditional Statements
    • Converse: If q is true then p is true or q → p
    • Inverse: If p is not true then q is not true or ~p →~q
    • Contrapositive: If q is not true then p is not true or ~q → ~p
