Triangle Congruence

Chip Rollinson, Sarah Ellis, 30/04/2020

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


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

1.

Angle Angle Angle (AAA)

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.
Angle Angle Angle (AAA)
Is AAA enough to prove triangles congruent? If not, why not?
