A scalene triangle
yes
It is a scalene triangle
yes it is possible.
Yes.
To create a triangle, the sum of the two shorter sides must be greater than the third side. If the side of length 11 is the longest side then the missing side must be greater than 11 - 8 = 3 If the missing side is the longest side then the missing side must be less than 8 + 11 = 19 Thus any length that is greater than 3 and less than 19. Examples include: 4, 5, 10, 17

11, 4, 8
No because the sum of the its 2 smaller sides must be greater than its longest side.
Yes.
Yes and it will be a scalene triangle
Yes, because 11 + 15 > 21, 11 + 21 > 15, and 15 + 21 > 11
No it is not possible because the sum of the lengths of the two sides has to be greater than the length of the third side. 5 + 4 = 9 which is less than 11, so we can't form a triangle with these sides.
Yes that is possible. To check, you add the two shorter sides, and they should be longer than the longest side.
No. One of the sides is longer than the other two combined. If the side which is 29 is AB then the side connected to it at A will never be able to meet the side connected to it at B.
9, 4, and 11 are three dimensionless numbers. Yes, they can represent the lengths of the sides of a triangle. You can take three straight sticks, cut them to lengths of 9, 4, and 11 inches, then lay them down on a table so that the ends hook up and they form a triangle.
