The second one I was right but my reasoning was wrong I didn’t read it correctly. The last one is where you add the two that are less than the greatest number and if the sum is bigger than the greatest number, it forms a triangle. That says SIDES I thought all of them said sides but the first and second ones are angles. If you add all the angles and they all add up to 180 degrees, then it forms a triangle. Sorry for the wrong reasoning.
The answer is D. This is because a triangle must be 180 degrees, and both A and B are equal to 180. For the sides, you simply follow a squared plus b squared equals c squared. D doesnt fit that equation, so the answer is D.
