Triangle Congruency: SSS and SAS Concepts

What are the two main theorems used to determine if triangles are congruent?

• Angle-Side-Angle (ASA) and Angle-Angle-Side (AAS)

• Side-Side-Side (SSS) and Side-Angle-Side (SAS)

• Side-Angle-Side (SAS) and Angle-Side-Angle (ASA)

• Side-Side-Side (SSS) and Angle-Angle-Angle (AAA)

What is the significance of vertical angles in proving triangle congruency?

• They are always different and cannot be used in any theorem.

• They are always equal and can be used in the SAS theorem.

• They are used to prove that triangles are similar, not congruent.

• They are only used in the SSS theorem.
