Question

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?

Answer 1

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

Answer 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.

Answer 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.
