  • Midpoint Formula Warm Up Graph  quadrilateral  BOAT  given  the  coordinates  B(-‐5,2),  O(-‐1,3),  A(1,-‐5),  and  T(-‐3,-‐6).    

    a.  Find  the  length  of  each  side:     BO     OA     AT     TB    b.  Find  the  slope  of  each  side:     BO     OA     AT     TB    c.  Find  the  length  of  the  diagonals:     d.    Find  the  midpoint  of  the  diagonals:     BA               BA     OT               OT    

    Finding the Midpoint Formula 1.    Find  the  midpoint  of  the  following  blue  line  segment.    

    2.    Graph  the  following  sets  of  points  and  find  the  midpoint  of  the  line  segment  created  by  connecting  the  two  points.  𝐶(0,−5)  to  𝐷(6,−1)  

     

    Midpoint  Formula  Given  two  endpoints  of  a  line  segment  (𝑥!, 𝑦!)  and  (𝑥!, 𝑦!),  the  midpoint:  

    𝑀 = (          +          2 ,

             +          2 )  

  • Find  the  midpoint  of  each  segment  with  the  given  endpoints.    1.    𝐴(−1,5)  &  𝐵(3,1)           2.    C(−4,7)  &  𝐷(−8,−2)            Given  the  midpoint  and  one  endpoint  of  a  line  segment,  find  the  other  endpoint.    3.    Endpoint  (−9,−1),  midpoint  (8,14)       4.      Endpoint  (10,12),  midpoint  (6,9)          5.    The  endpoints  of  the  diameter  of  a  circle  are  given  by  (-‐1,5)  and  (4,-‐3).    What  is  the  center  of  the  circle?    

    Midpoint / Distance HW  Find  the  distance  AND  midpoint  between  each  pair  of  points.    1.    (14,0)  &  (−4,8)                 2.    (−4,12)  &  (−7,−2)                    3.    𝐴𝐵  is  the  diameter  of  a  circle.    The  coordinates  of  A  are  (17,−1)  and  the  coordinates  of  B  are  (10,−9).    What  are  the  coordinates  of  the  center  of  the  circle?        4.    If  the  midpoint  of  a  line  segment  is   3,4  and  one  of  the  endpoints  is  (7,16),  find  the  coordinates  of  the  other  midpoint.        5.    Imagine  a  coordinate  plane  was  placed  on  the  Panther’s  football  field.    For  a  certain  play,  if  Steve  Smith  is  located  at  (0,  4)  and  Cam  Newton  is  located  at  (−2,  −4),  how  far  apart  are  they?
