3.2: Triangle Side Lengths & Angles

Caroline Psutka, Mrs. Park, 23/03/2024

What consecutive parts about side lengths and angles of triangles do we need to make one unique triangle? These applets allow students to explore whether triangle relationships (SSS, AAA, SAS, HL, SSA, ASA, AAS) that make unique triangles.


  • 1. SSS (Side-Side-Side): 3 Side Lengths
  • 2. AAA (Angle-Angle-Angle): 3 consecutive angles
  • 3. SAS (Side-Angle-Side): 2 sides & angle in between
  • 4. SSA(Side-Side-Angle): 2 sides & angle not in-between
  • 5. ASA(Angle-Side-Angle): 2 angles & a side in between
  • 6. AAS(Angle-Angle-Side): 2 angles & side not in-between
