What is the rule for 3 sides of a triangle?
Triangle Inequality Theorem. The sum of the lengths of any two sides of a triangle is greater than the length of the third side.
How many possible integer lengths has the third side?
The sum of the lengths of 2 sides of a triangle must be greater than—but not equal to—the length of the third side. Further, the third side must be longer than the difference between the greater and the lesser of the other two sides; therefore, 20 is the only possible answer.
Can you find a right triangle whose side lengths are consecutive natural numbers?
A right triangle has side lengths that are consecutive even integers. *Note: Consecutive even integers are even integers that follow each other. They have a difference of 2 between every two numbers. If “n” is an even integer, then n, n + 2, n + 4, and n + 6 will be consecutive even integers.
Do all right triangles have lengths that are integers?
A Pythagorean triple consists of three positive integers a, b, and c, such that a2 + b2 = c2. The name is derived from the Pythagorean theorem, stating that every right triangle has side lengths satisfying the formula a2 + b2 = c2; thus, Pythagorean triples describe the three integer side lengths of a right triangle.
What is the sum of all 3 sides of a triangle?
The sum of three sides of a triangle is known as perimeter. Perimeter of triangle is the total length of boundary of the triangle which is equal to the sum of three side lengths .
What are the rules for the sides of a triangle?
The sum of the length of any two sides of a triangle is greater than the length of the third side. The side opposite to the largest angle of a triangle is the largest side. Any exterior angle of the triangle is equal to the sum of its interior opposite angles.
How do you find the possible length of the third side of a triangle?
The Triangle Inequality theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.
- So, difference of two sides
- Therefore, 9−3

Which three lengths Cannot be the sides of a triangle?
Sat Mathematics : Example Question #6 A triangle has sides of length 8, 13, and L. Which of the following cannot equal L? Explanation: The sum of the lengths of two sides of a triangle cannot be less than the length of the third side.
What 3 numbers can form a right triangle?
The three numbers 4, 5, 6 make a Pythagorean Triple (they could be the sides of a right triangle).
Does 1/2 and 3 make a right triangle?
Thus, 1,2,3 is not a Pythagorean triple and sides of such lengths cannot form a right triangle.
