Worksheet 4-2 from yesterday • Finish worksheet (9-11) • Complete new worksheet today
Section 4-3 Using Congruent Triangles
What is different in this section? • Complete the proofs like you have done in section 4.2, just now that you’ve proved triangles are congruent (using either SSS, SAS, ASA) any part of a triangle that you state that is congruent, your reason is CPCTC!
Finish back of new worksheet • Cross out line #5 in the second proof • Cross out line #6 in the third proof
