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.

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.
What could be the length of the third side of a triangle that has two sides of lengths 4 and 15?
For a triangle to exist, the sum of the two shorter sides must be longer than the longest side. If 15 is the longest side, then the other, missing, shorter side must be greater than 15 - 4 = 11. If the third, missing, side is the longest side, then it must be less than 15 + 4 = 19 So the third side is any length greater than 11 and less than 19. Examples include 12, 13, 15, 11.5, 18.5.
How do you describe the possible lengths of the third side of a triangle when the other tw sides are given?
The length of the third side must be greater than the difference between the length of the two given sides and it must be less than the sum of the two given sides. These limits can be derived from the fact that any two sides of a triangle must have a combined length greater than the third side.
How do you find if the lengths of a shape make a triangle?
If (and only if) the length of each pair of sides is greater than the third side, then it is possible to make a triangle.
what- Two sides of a triangle measure 8 cm and 15 cm.What is the least possible length of the third side if the length is a whole number?
8cm
What is the minimum and maximum length of the third side of a triangle with sides 11 and 28?
The minimum length possible is 18. The maximum is 38.
If two sides of a triangle equal 45 what does the third equal and what kind of triangle is this?
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.
What is the length of the third side of an equilateral triangle have?
The length of the third side of an equilateral triangle is the same as the lengths of both of the other two sides.
Is it possible to build a triangle with side lengths of 7 6 and 9?
Yes It is. Try it. All the sides of a triangle don't have to of equal length. -Cody Dunn Also, as long as the sum of any two sides exceeds the length of the third side, the three sides can build a triangle. This is false!
what- Two sides of a triangle measure 7 ft and 12 ft.What is the greatest possible length of the third side if the length is a whole number?
18 ft
Is it possible to form a triangle with the given side length 3 4 8?
Sum of any two sides of a triangle is greater than third side. 3 + 4 = 7 < 8, but 7 is less than 8. So, it is not possible to form triangle with sides of length 3, 4 and 7 units.
What is the rule for the triangle in length and width?
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.
What is the third side an isosceles triangle?
An isosceles triangle has 3 sides 2 of which are equal in length
What is isoselis triangle?
An isosceles triangle is one in which two sides are of the same length, but the third is different.
