3.6 Pythagorean Theorem Warm-up (IN) 1.Find the area of a square whose sides are 10 units long. 2. The square of what number is 2704? 3. Evaluate each expression: Learning Objective: to find the lengths of the sides of a right triangle, and to decide if a triangle is right, obtuse, or acute. 100 square units

Notes Pythagorean Thm - In a right, the sum of the squares of the lengths of the legs is equal to the square of the hypotenuse. Learning Objective: to find the lengths of the sides of a right triangle, and to decide if a triangle is right, obtuse, or acute. a b c Ex 1 – Find the missing side of the triangle a. a=12, b=16b. b=, c=13 Exploration p. 148

Ex 2 – Simplify Already simplified Converse of the Pythagorean Thm - CKC p. 150 Learning Objective: to find the lengths of the sides of a right triangle, and to decide if a triangle is right, obtuse, or acute.

HW – p. 144 #1-23 odd p. 150 #1-8 Out – how can you classify a triangle based on the side lengths? Summary – Today, I understand… POW!!
