Correct.

anonymous · Answer

does it make a difference this cus theres an option just like this but i dont understand . its the same but with line under the (<)

anonymous · Answer

That means less than or equal to. That option won't make sense because:
Any side of a triangle cannot be equal to or less than the difference of the other two sides.
AND
Any side of a triangle cannot be equal to or greater than the sum of the other two sides.

anonymous · Answer

In this case, 0 is not even a possible value of a side. So, it can never be that "less than or equal" option.

hm then il just go with my first option thank u very much

Notice that the 3rd side can stretch as far as the sum of the two other sides (not be equal or greater).
