Question

Could 4.1 cm, 8.4 cm and 1.3 cm be the side lengths of a triangle? A Yes B No

Answer 1

No, the three given side lengths could not make a triangle.

8.4 cm is greater than 4.1 cm and 1.3 cm combined, so no matter what angle is between the two shorter sides, it is impossible to fit the 8.4 cm side.
