A primitive Pythagorean triple has side lengths that are coprime, meaning they share no common divisors other than 1. Non-primitive Pythagorean triples can be generated by multiplying all sides of a primitive triple by a common integer.<\/p>\n\n\n\n<ol class=\"wp-block-list\" start=\"2\">\n<li>What are some common examples of Pythagorean triples?<\/li>\n<\/ol>\n\n\n\n<p>Some common examples of Pythagorean triples are (3, 4, 5), (5, 12, 13), (7, 24, 25), and (8, 15, 17). These are primitive Pythagorean triples, as their side lengths share no common divisors other than 1.<\/p>\n\n\n\n<ol class=\"wp-block-list\" start=\"3\">\n<li>Can a Pythagorean triple have an odd hypotenuse?<\/li>\n<\/ol>\n\n\n\n<p>No, a Pythagorean triple cannot have an odd hypotenuse. The hypotenuse (c) will always be even since, according to Euclid&#8217;s formula, c = m\u00b2 + n\u00b2. Since the sum of two odd numbers is even, and the sum of two even numbers is also even, the hypotenuse will always be even.<\/p>\n\n\n\n<p><strong>Related Articles<\/strong><br><a
