Find he number of distinct triangles with integer sides and perimeter 10 that can be constructed.

  • Math -

    1,1,8
    1,2,7
    ...
    1,4,5
    all bad, because each side must be less than the sum of the other two sides.

    So, list all the other possibilities and check them out.

    Then would it be 2 distinct triangles?

    That's what I get.

    2,4,4
    3,3,4

    Same. Thank you
