  1. 4.3 Proving Triangles are Congruent Side-Side-Side Side-Angle-Side

  2. Side-Side-Side If three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent.

  3. Side-Angle-Side If two sides and an angle between the sides are congruent in two different triangles, then the triangles are congruent.
