Learn about the four ways to check for triangle congruence.
  • What are SSS, SAS, ASA, and AAS in Geometry?
  • How do you prove that two triangles are congruent?
  • What is the difference between AAS and ASA?
  • How do you write a two-column proof of triangle congruence?
  • Given that S is the midpoint of QT and QR is parallel to TU, how do you prove that triangle QSR is congruent to triangle TSU?
  • What does it mean when two parallel lines are cut by a transversal?
  • What is true about alternate interior angles?
  • How do you start a triangle congruence proof?
  • What is the first statement in a congruence proof?
  • What do you write under the reason column in a two-column proof?
This is a great review lesson for anyone struggling with proving triangle congruence. Not only do you see how to write a two-column proof for a specific example of two triangles, but you will learn all the reasoning behind the statements and why it works.
