3. 4. The area of a square is 64 square inches. What is the length of the square?

4. 5. If 3 out of 7 students did not calculate the number of neutrons in Oxygen correctly, what percent did calculate correctly?

5. Quiz 1-4-11 A triangle has sides 4, 7, and 10. Is this triangle a right triangle?

6. Is it a right triangle? To determine if it is a right triangle, I used the Pythagorean theorem. If the theorem is proven, then the triangle is a right triangle. I plugged the numbers into the theorem (10 had to be c because it is the longest side). I squared the legs and added them together. I compared that the square of the hypotenuse. A triangle has sides 4, 7, and 10. Is this triangle a right triangle? The triangle is not a right triangle. Triangle Sides: 4, 7, 10 Not a right triangle

10. Class Work: Pythagorean Theorem You need your notes. Title the notes: Pythagorean Theorem I will check your work at the end of class.

11. Pythagorean Theorem Leg Hypotenuse Legs: Sides a and b Hypotenuse: Always side c

12. Pythagorean Theorem a b c Theorem: a 2 + b 2 = c 2

13. Pythagorean Theorem You are decorating the diagonal of a 12 inch by 7 inch window. How much material is needed to decorate the diagonal? HINT: Draw a picture

14. Pythagorean Theorem 7 12 c Theorem: a 2 + b 2 = c 2 7 2 + 12 2 = c 2 49 + 144 = c 2 193 = c 2 Guess & Check 13.9 13.9 = c

15. Pythagorean Theorem The two sides of an isosceles triangle are 8 in. The height of the triangle is 7 in. Calculate the base of the triangle. Calculate the perimeter of the triangle. HINT: Draw a picture 8 in 7 in 8 in

16. Pythagorean Theorem Theorem: a 2 + b 2 = c 2 7 2 + b 2 = 8 2 49 + b 2 = 64 -49 b 2 = 15 3.9 in b = 3.9 in base= 7.8 in 3.9 in 8 in 7 in 8 in P = 2(8)+7.8 in P = 23.8 in

17. Pythagorean Theorem If a 2 + b 2 = c 2, then the triangle is a right triangle. If a 2 + b 2 = c 2, then the sides are Pythagorean triples. a=6, b=9, c=10 6 2 + 9 2 = 10 2 36+ 81 = 100 117 = 100 Not a right triangle 6, 9, 10 are Not Pythagorean Triples

18. Pythagorean Presentation Create a Powerpoint slide show over the Pythagorean Theorem Describe what the theorem is. Include your picture of an example of a right triangle. You must have 5 slides over the Pythagorean Theorem Outline on paper today. You will create your slide show tomorrow. Work on your sing-a-long project after you have outlined your powerpoint.
