Answers

  1. Answer:
    2, 6, and 7
    Yes, the smallest 2 sides sides add up to be larger than the longest side.
    3, 3, and 3
    Yes, any 2 sides sides add up to be larger than the other side. These sides would form an equilateral triangle.
    5, 7, and 12
    No, the smallest 2 sides sides do not add up to be larger than the longest side. 5 and 7 add up to be equal to 12 but not larger.
    Step-by-step explanation:
    If the 2 smallest sides of a triangle add up to be larger than the longest side, then the sides can create a triangle.
