What are Pythagorean Triples?
Pythagorean triples are sets of three positive integers a, b, and c, such that a^2 + b^2 = c^2. These triples are named after the ancient Greek philosopher and mathematician Pythagoras, who is credited with their discovery. Pythagorean triples have numerous applications in mathematics, physics, and engineering, and are a fundamental concept in geometry and trigonometry.
Leon's Procedure for Verifying Pythagorean Triples
Leon, a mathematician, has developed a procedure for verifying whether a given set of side lengths forms a Pythagorean triple. The procedure involves three steps:
Step 1: Find the Greatest Common Factor (GCF) of the Given Lengths
The first step in Leon's procedure is to find the greatest common factor (GCF) of the given side lengths. The GCF is the largest positive integer that divides each of the given numbers without leaving a remainder. In the case of the side lengths 21, 28, and 35, the GCF is 7.
Why is the GCF important?
The GCF is important because it allows us to simplify the given side lengths and make it easier to verify whether they form a Pythagorean triple. By dividing the given side lengths by the GCF, we can obtain a new set of side lengths that are more manageable and easier to work with.
Step 2: Divide the Given Lengths by the Greatest Common Factor
Once we have found the GCF, we can divide the given side lengths by the GCF to obtain a new set of side lengths. In the case of the side lengths 21, 28, and 35, dividing by 7 gives us the new side lengths 3, 4, and 5.
What do these new side lengths represent?
The new side lengths 3, 4, and 5 represent a simplified version of the original side lengths. These new side lengths are more manageable and easier to work with, and they can be used to verify whether the original side lengths form a Pythagorean triple.
Step 3: Verify the Pythagorean Triple
The final step in Leon's procedure is to verify whether the new side lengths form a Pythagorean triple. This involves checking whether the sum of the squares of the two shorter side lengths is equal to the square of the longest side length. In the case of the side lengths 3, 4, and 5, we have:
3^2 + 4^2 = 9 + 16 = 25 5^2 = 25
Since the sum of the squares of the two shorter side lengths (3 and 4) is equal to the square of the longest side length (5), we can conclude that the side lengths 3, 4, and 5 form a Pythagorean triple.
Conclusion
Leon's procedure for verifying Pythagorean triples is a simple and effective method for determining whether a given set of side lengths forms a Pythagorean triple. By finding the greatest common factor of the given side lengths, dividing the given side lengths by the GCF, and verifying the Pythagorean triple, we can determine whether a given set of side lengths is a Pythagorean triple.
