If two sides of a triangle are 9 and 21 which is not a possible length for the third side?
the sum of two sides of the triangle should not be greater than the third side so it can not be less than 9 or higher than 30, also according to the second law.. in case of right angle traingle the square of two sides of a traingle shuld be equal to the third side.. here we dont know what type of triangle are you talking about so we need to expalin both the cases.

What could be the length of the third side of a triangle that has two sides of lengths 7 and 12?
Oh, what a happy little triangle we have here! To find the possible length of the third side, we can use the triangle inequality theorem. The third side must be greater than the difference between the other two sides and less than the sum of the other two sides. So, the third side could be any length between 5 and 19 units.
Is a 5cm by 12cm a right triangle?
If two sides of a triangle have lengths of 5cm and 12cm, then the third side can have any length that's more than 7cm and less than 17cm. If the third side is 13cm, then the triangle is a right triangle.
Can three sides of 25m 15m and 5m form a triangle?
Triangle inequality says that the sum of the lengths of any two sides of a triangle is greater than the length of the third side.Since 15 + 5 = 20 < 25, we cannot draw a triangle.
How can you prove that the is the sum of the lengths of any two sides of a triangle always greater than the length of the third one?
Simply measure them.
Triangle has two sides of length 4 and 15 What value could the length of the third side be?
The third side must be longer than 11 and shorter than 19.
