Presentation Transcript

  1. Period C/D • Please write your name on the California Content Standards Mathematics Practice bubble sheet. • Show work on a lined piece of paper. Keep this paper with your bubble sheet to use every day until the CST Test. Be neat on your scratch paper, number your problems. • Please DO NOT write in the test book. • Then do p.1 #1-6 • Have out HW(p.562 #16-35), book, red pen, pencil on desk.

  2. The Pythagorean Theorem p.564 c a • Legs- the twoshortest sides of a right triangle. (a and b) • Hypotenuse- the longest side of a right triangle that is opposite the right angle. (c) b

  3. The Pythagorean Theorem c a For any right triangle: b

  4. Example Find c, the length of the hypotenuse, in the triangle. c 6 cm 8 cm

  5. Example Find c, the length of the hypotenuse, in the triangle. c 6 cm 8 cm

  6. Example Find c, the length of the hypotenuse, in the triangle. c 6 cm 36 + 64= c2 8 cm

  7. Example Find c, the length of the hypotenuse, in the triangle. c 6 cm 36 + 64= c2 100 = c2 8 cm

  8. Example Find c, the length of the hypotenuse, in the triangle. c 6 cm 36 + 64= c2 100 = c2 8 cm

  9. Example Find c, the length of the hypotenuse, in the triangle. c 6 cm 36 + 64= c2 100 = c2 8 cm 10 = c

  10. Try This Find the length of the missing side of a right triangle. Legs: 3 ft and 4 ft c 3 ft 4 ft

  11. Try This Find the length of the missing side of a right triangle. Legs: 3 ft and 4 ft c 5 ft. 3 ft 4 ft

  12. Find the length of the missing side. (Hint: is x an a, b, or c?) x 3 in. 5 in.

  13. x = b Find the length of the missing side. (Hint: is x an a, b, or c?) x 4 in. 3 in. 5 in.

  14. Pythagorean Theorem Review g h i g and h • Which sides of the right triangle are the legs? • Which side of the right triangle is the hypotenuse? • What is always the longest side of any right triangle? • 4) Besides being the longest side, how else do you know that i is the hypotenuse of this right triangle? • 5) What is the formula for the Pythagorean Theorem? i The hypotenuse It is opposite (or across from) the right angle.
