  1. What are the four standard conditions for proving triangles are congruent?

    Show answer

    SSS (Side-Side-Side), SAS (Side-Angle-Side), ASA (Angle-Side-Angle), and RHS (Right angle-Hypotenuse-Side).

  2. Can AAA (three equal angles) be used to prove two triangles are congruent?

    Show answer

    No, AAA cannot prove congruence. It can only prove that triangles are similar (same shape but potentially different size).

  3. What does RHS stand for in triangle congruence?

    Show answer

    Right angle-Hypotenuse-Side.

  4. In SAS congruence, must the angle be between the two equal sides?

    Show answer

    Yes, the angle must be the included angle between the two sides.
