Objective & Vocabulary • 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 B=20 • Find c. • If a=9 ft, b=12 ft, find c. A=15 C=?
Example 2: Finding the Length of a Leg • Find b. • Find a if b=12ft and c=20ft. 5 ft. 3 ft. b
