If the perimeter of a triangle is 12, which of the following could be the length of one side of the triangle?
Would the correct answer be d. 5?
And how do you go about answering this type of question? I just guessed; I figured it was the smallest number.. and 8 was too long to be a side.
You did it correctly. you look at the other two sides, they have to be greater than the side given. If a is a side, then b+c must be greater than a.
