Answer:
D. the lengths of all the sides
Step-by-step explanation:
Consider the triangle congruence theorems. They are abbreviated ...
- SSS
- SAS
- ASA
- AAS
- HL (right triangle only)
Matching these with the offered choices, you find that SSS (the lengths of 3 sides) is the only one that compares. The other offered choices are insufficient to completely define a unique triangle.
___
Two or three angles will define a triangle, but not one that is unique. The size of it is not determined by the angles alone.
