Question

Is it possible to construct a triangle with the given side lengths? If not, explain why not 28, 34, 39

hintHint:

  • Triangle inequality theorem
  • According to this theorem, in any triangle, sum of two sides is greater than third side,
  • a < b + c
  • b < a + c
  • c < a + b

The correct answer is: Yes, it is possible to construct triangle with this sides.


    • Step-by-step explanation: 
    • Given:
    In triangle, sides are 28 cm, 34 cm and 39 cm.
    a = 28, b = 34, and c = 39.
    • Step 1:
    • First check validity.
    According to triangle inequality theorem,

    a < b + c,

     28 < 34 + 39

    28 < 73, True

     b < a + c,

    34 < 28 + 39,

     34 < 67, True

    c < a + b,

    39 < 28 + 34

    39 < 62, True
    As sides of triangle satisfy triangle inequality theorem.
    Hence, triangle can be constructed with this sides.

    • Final Answer: 
    Yes, it is possible to construct triangle with this sides.
