Wednesday, Dec. 18 at 4:00 - The final deadline for turning in assignments.
Proofing practice!
Prove that ∆ABC ≅ ∆QDE
Statements Reasons
Line AC ∥ line DQ Given
Line ED ∥ line BC ∠GEF ≅ ∠CFE, if alternate interior angles are congruent, then the lines are parallel because the corresponding angles are congruent.
∠FCE ≅ ∠GEA ≅ ∠GDB Corresponding angles/Alternate interior angles
∠FEG ≅ ∠GBF Euclid's postulate #4
Line ED ≅ line CB Reflexive argument based upon line AC ∥ line DQ and
line ED ∥ line BC are parallel
∆ABC ≅ ∆QDE ASA
