COMMON PYTHAGOREAN TRIPLES AND SOME OF THEIR MULTIPLES The most common Pythagorean triples are in bold. The other triples are the result of multiplying each integer in a bold face by the same factor.

Slide 12

PRACTICE: The given lengths are two sides of a right triangle. All three side lengths of the triangle are integers and together form a Pythagorean triple. Find the length of the third side and tell whether it is a leg or a hypotenuse.
