Yes. What you should watch out for is that, to form a triangle, none of the segments should be longer (or as long as) the other two segments combined. Just check whether the longest segment is longer than the sum of the other two - if it is, then you can't form a triangle.
yes
No. In order for any three line segments to form a triangle, none of them can be greater in length than the sum of the other two.
that's not a triangle
Turn the 7 to form an angle with the other 7. It shapes a triangle.
Those segments can form a triangle because the two smallest sides, 7 and 8, add together to make 15, which is greater than the longest side, 12.
Yes they could.

Yes.
yes
No. Any two sides of a triangle MUST add up to more than the third. 8+7 = 15, not > 15.

Turn the 7 to form an angle with the other 7. It shapes a triangle.
Yes and it will be in the form of an isosceles triangle having two equal sides.
15/7 is in its simplest form.
7/15 in decimal form = 0.4666...7/15:= 7 ÷ 15= 0.4666... in decimal
