We have one side as 8. By the triangular inequality, the other two sides must
have a larger sum than 8. So the smallest their sum can be is 9. So the smallest
possible perimeter is 8+9=17.
There are four possible triangles with that perimeter and positive whole numbers
for sides. They are:
1,8,8 (an isosceles triangle)
2,7,8
3,6,8
4,5,8
In each case the perimeter is 17.
