Answer:
D
Step-by-step explanation:
As stated elsewhere, two conditions must be met.
- There are 3 angles in a triangle.
- They must add to 180
Answers A B and C all meet these 2 conditions. It is only D that gives you the problem.
It adds to 181 which is not 180. 180 is written in stone, A triangle cannot have 179 degrees, nor can it have 181 degrees.
It must have 180.
D has 181 degrees. It cannot be a triangle.
