Math  8:  The Pythagorean Theorem Project (TPTP)!  

 In  this  project  you  will  learn  about  one  of  the  most  famous  theorems  know  to  ancient  civilizations…  The  Pythagorean  Theorem!      You  need  to  complete  the  following  three  parts.    You  are  given  Parts  1  and  2  in  this  booklet.    You  will  need  to  attach  Part  3.  

Part 1: Applying the Pythagorean Theorem                                                                                  Part  1  DUE:              

 Complete  questions  1  through  6  in  the  packet  to  demonstrate  how  you  can  use  the  Pythagorean  Theorem  to  find  a  missing  length  through  real-­‐world  applications.    Answer  the  following  questions  as  you  explain  the  process  of  finding  the  answer:    

1.  How  is  the  right  triangle  formed?    In  other  words,  describe  the  lines  that  make  leg  “a”  and  leg  “b”  and  the  hypotenuse  “c”  of  the  right  triangle.      2.    What  is  the  missing  length?    Is  it  one  of  the  legs  or  is  it  the  hypotenuse?    3.    How  do  you  find  the  missing  length?  

     Part 2: Pythagorean Theorem in your life.

 Part  2  DUE:              

Describe  how  you  may  use  the  Pythagorean  Theorem  in  your  life.  You  need  to  give  at  least  2  examples  and  “math  class”  cannot  be  one  of  them.        Part 3: The ‘interesting’ information

 Part  3  DUE:              

 This  is  not  included  in  your  attached  packet.    You  will  need  to  attach  it  before  handing  it  in.    You  must  include:    

1.  A  picture  of  Pythagoras    2.  A  definition  of  the  Theorem    3.  A  ‘Pythagorean  Tree’  like  you  made  in  Activity  #1:  Cut  and  paste…    4.  An  example  of  how  to  apply  the  Theorem    5.  One  extra  piece  of  ‘interesting’  information  about  Pythagoras  and/or  his  theorem.
