1.The midpoint of SM is (5 -11) one endpoint is S (3,5). What are the coordinates of endpoint M?

2.Describe a process you would use to create the perpendicular bisector to a segment AB using only an unmarked straightedge and an unmarked compass.

3. How is constructing a perpendicular bisector similar to constructing an angle bisector? how is it different?

  1. in x 3 ---> 5 ---> 7 up 2
    in y 5 --> -11 --> -27 down 16
    so
    (7 , -27)

  2. Hey, check any old geometry text
    swing compass from each end with radius around 3/4 of your segment length
    connect the two points where the circles cross.

  3. LOL, you swing the compaas twice along each side for the angle bisector. (at the intersection you get two for one)
    Like I said, just Google this or look at ANY geometry book.
