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.

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.

9
PRACTICE: Find the area of the isosceles triangle. Use Pythagorean theorem to find h Use Area of a triangle

11
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.

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.
