What must you do to determine if side lengths can make a triangle?

• Add the two shorter sides, answer must me less than or equal to the third side

• Subtract the largest side from any other side and the answer must be positive

• Add the two shorter sides together, answer must be larger than the third side

• Divide your largest side by one of the shorter sides, your answer has to be bigger than the remaining side.

Name the postulate, if possible, that makes the triangles congruent.
