Triangle Congruence

Chip Rollinson, Shelley Burnside, 17.10.2020

Test whether each of the following "work" for proving triangles congruent: AAA, ASA, SAS, SSA, SSS, HL


  • 1. Side Side Side (SSS)
  • 2. Angle Angle Angle (AAA)
  • 3. Angle Side Angle (ASA)
  • 4. Side Angle Side (SAS)
  • 5. Side Side Angle (SSA)
  • 6. HL Postulate exploration

1.

Side Side Side (SSS)

Drag the red points in the top half of the drawing to adjust the givens, then adjust the points to try to make congruent or non-congruent triangles in the bottom half.
Side Side Side (SSS)
Is SSS enough to prove triangles congruent? If not, why not?
