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

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