Answer 1

Answer:

Yes, the sides are possible to construct a triangle.

Step-by-step explanation:

Add the 2 smallest sides and if they are bigger than the biggest side then it is a triangle.

Answer 2

Answer:

Yes. This is possible.

Step-by-step explanation:

The vital condition of a triangle is that any 2 sides need to add up to make a value greater than the third side. In the values given, these are the sums which all suggest these lengths can form a triangle:

8.5 cm + 6 cm = 14.5 cm which is greater than the third side of 7 cm.

7 cm + 6 cm = 13 cm which is greater than the third side of 8.5 cm.

8.5 cm + 7 cm = 15.5 cm which is greater than 6 cm.

All of these sums suggest these lengths can make a triangle.
