11-3: The Pythagorean Theorem Pg.546

Objective & Vocabulary 1.Find the length of a side of a right triangle. Hypotenuse (pg.546): in a right triangle, the side opposite the right angle (the longest side) is the hypotenuse. Leg (pg.546): the two sides in a right triangle that form the right angle. Pythagorean theorem (pg.546): for any right triangle, the sum of the squares of the lengths of the legs equals the square of the length of the hypotenuse [ ].

Example 1: Finding the Length of a Hypotenuse A.Find c. B.If a=9 ft, b=12 ft, find c. A=15 B=20 C=?

Example 2: Finding the Length of a Leg A.Find b. B.Find a if b=12ft and c=20ft. 3 ft. 5 ft. b
