a triangle has sides of lengths 12, 14, and 19 is it a Right Triangle? Explain

  • Geometry -

    it is a right triangle only if

    19^2 = 12^2 + 14^2

    since
    12^2 ends in 4
    14^2 ends in 6
    19^2 ends in 1
    it is not possible.

  • Geometry -

    it is not a right triangle. the easiest way i determine is if they are factors of 3,4 and 5
