Triangles congruent by ASA and AAS proofs - Congruence

Intro Lesson

• a)

  1. Similar tirangles VS. Congruent triangles
  2. Ways to prove congruency:
  • SSS
  • SAS
  • ASA
  • AAS

• a)

  $\overline {AB}$$\cong$$\overline {DE}$ and $\angle C$$\cong$$\angle F$
  Prove by AAS.

• b)

  $\overline {AC}$$\cong$$\overline {DF}$ and $\angle A$$\cong$$\angle D$
  Prove by ASA.

• c)

  $\angle A$$\cong$$\angle D$ and $\angle B$$\cong$$\angle E$
  Prove by AAS.

• a)

  $\triangle ABC$, $\triangle CBD$
  
  

• b)

  $\triangle XYZ$, $\triangle XWZ$
