Triangle Congruence Investigation

Caroline Psutka, Morgan, 29/10/2024

What consecutive triangle parts need to be congruent in order to show that two triangles are congruent? These applets allow students to explore whether triangle relationships (SSS, AAA, SAS, SSA, ASA, AAS) force triangles to be congruent or not. Are you able to create a non-congruent pair of triangles?


  • 1. SSS
  • 2. AAA
  • 3. SAS
  • 4. SSA
  • 5. ASA
  • 6. AAS

Three sides of the same length - drag the two points on the second figure so that they connect and form a triangle.
