The sum of the two shorter sides of a triangle must be longer than the third.
Thus the third side can be any length greater than 0 and less than 20.
Examples are 0.5, 2, 5, 10, 15, 17.5, 19.9.
A triangle has two sides of lengths 7 and 9. what value could the length of the third side be?
The length of the third side of an equilateral triangle is the same as the lengths of both of the other two sides.

It could be 12 because the sum of the 2 smaller sides of a triangle must be bigger than its largest side.
If any of its 2 sides is not greater than its third in length then a triangle can't be formed.
A triangle has two sides of lengths 7 and 9. what value could the length of the third side be?
The length of the third side of an equilateral triangle is the same as the lengths of both of the other two sides.
If two sides of a triangle each have length of 45 units, then the triangle is isosceles,and the third side can have any length less than 90 units.
A triangle has 3 sides. The sum of any two sides must be larger than or equal to the length of the third side, and the difference of any two sides must be less than or equal to the length of the third side.
An isosceles triangle has 3 sides 2 of which are equal in length
An isosceles triangle is one in which two sides are of the same length, but the third is different.
The length of the third side is the same as the length of either of the other two sides.

The perimeter is the sum of the three sides.
