Answer 1

Answer:

the 3rd one

Step-by-step explanation:

Answer 2

Answer:

A) 12 cm, 7 cm, 5 cm

Step-by-step explanation:

For the side lengths of a triangle to be true, the smaller side lengths can not add up to be smaller or equal to the larger side length. In this case, the smaller lengths are 7 and 5. Add them to get 12, the same side length as the largest side. The smaller sides (7 and 5) add to be equal to the longer side length, so these side lengths are FALSE. The other 3 sides of triangles are TRUE.
