The sum of the 2 shorter sides must be greater than the longest side to form a triangle
Any number between 3 and 15
The last side length could be between 4 units and 10 units inclusive.
A triangle formed from three given side lengths can be either unique or non-unique depending on the specific lengths. If the triangle inequality theorem is satisfied (the sum of the lengths of any two sides must be greater than the length of the third side), then only one unique triangle can be formed. However, if the side lengths are such that they can form a degenerate triangle (where the sum of two sides equals the third), or if two sides are equal and the third side allows for more than one valid configuration (as in some cases with isosceles triangles), more than one triangle can potentially be formed. In general, for three distinct side lengths that satisfy the triangle inequality, only one triangle exists.
Yes and the given lengths would form an isosceles triangle.
An isosceles triangle must have two sides of equal size.Since you have a side of 7 and 5, for it to be isosceles, your third side must be either 7 or 5.
Any number between 3 and 15

If its a right angle triangle then its side lengths could be 3, 4 and 5
The length of the third side of an equilateral triangle is the same as the lengths of both of the other two sides.

The last side length could be between 4 units and 10 units inclusive.
The third side of a triangle must be greater than the absolute difference of the two given sides and less than the sum of the two given sides. In this case, the third side must be greater than |7-9| = 2 and less than 7+9 = 16. Therefore, the possible lengths for the third side of the triangle could be any value greater than 2 and less than 16.

That depends on what the side lengths are. Until the side lengths are known, the triangle can only be classified as a triangle.
An isosceles triangle must have two sides of equal size.Since you have a side of 7 and 5, for it to be isosceles, your third side must be either 7 or 5.
It says the sum of the lengths of any 2 sides of a triangle must be greater than the third side. Not equal to but GREATER than the third side.
