GE.C.1SSS, SAS, ASA, AAS, HL01/04
Triangle congruence postulates.
Step01of 04
Two triangles are congruent if all six corresponding parts (3 sides, 3 angles) match. But you don't need all six — just the right combination of three pieces.
| SSS | →three sides — AB≅DE,BC≅EF,AC≅DF |
| SAS | →two sides AND the angle BETWEEN them |
| ASA | →two angles AND the side BETWEEN them |
| AAS | →two angles AND a side NOT between them |
| HL | →right triangles only — Hypotenuse + one Leg |
