PYTHAGOREAN THEOREM: In a right triangle, the square of the
length of the hypotenuse is equal to the sum of the square of
lengths of the legs.
Slide 5
PRACTICE: Identify the unknown side as a leg or hypotenuse.
Then, find the unknown side length of the right triangle. Write
your answer in the simplest radical form.

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.
