Triangle Congruence

Chip Rollinson, Kelli Roskopf, 6 oct. 2023

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


  • 1. Side Side Side (SSS)
  • 2. Side Angle Side (SAS)
  • 3. Side Side Angle (SSA)

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?
