Answer:

  • A triangle with side lengths 3 cm. 5 cm. and 7 cm
  • A triangle with side lengths 4 cm, 5 cm. and 6 cm.​

Step-by-step explanation:

The sum of the short two sides must exceed the length of the longest side. That is not the case for lengths {4, 5, 15} or {5, 5, 10}.

Triangles can be formed from {3, 5, 7} and {4, 5, 6}.
