Midpoint Formula Extra Practice and Extension

							                                    Midpoint Formula Extra Practice and Extension

Name__________________________________

   1.   Given two points, what is the formula for finding the midpoint?



   2. Find the midpoint of the following pairs of points:
          a. (4,5) and (9,17)                  b. (2,8) and (6, 4)         c. (2,3) and (11,16)




   3. Challenge: Given the end point of (2,8) and midpoint of (4, 4) what is the other endpoint.




   4. Super challenge: If you have the endpoints from question 2a, and the midpoint is on a perpendicular bisector,
      what is the equation of the line that goes through the original two points, and what is the equation of the
      perpendicular line that goes through the midpoint?
