The given lengths won't form a triangle. The sum of the 2 smaller sides should be greater (not equal too) than the longest side.

so, the longest side her is 12ft

so the smaller sides are 4ft, and 8ft.

the sum of this two sides is 12ft which same as longest side (not greater)...

so it won't form a triangle, here it will just form points on lines.

Answer 2

No, the sum of the two smaller sides must be greater than the longer side.

In this case this would be just a straight line.
