Kathy uses the following steps to construct a perpendicular line through a point C on a line segment: Step 1: From point C, draw two arcs intersecting the line segment in points A and B. Step 2: Using slightly more compass width, draw two arcs from point A, one above and the other below the line segment. Step 3: Using the same width of the compass, draw two arcs from point B, above and below the line segment. Step 4: Label the point of intersection of the arcs above the line segment as F and below the line as E. Step 5: Using a compass, join E and F.

art A: Which is the first incorrect step? Part B: Using complete sentences, explain your answer for Part A. Part C: Explain why a compass works for the construction done by Kathy.
no compass, no way to completely understand the steps. Ok, let me try

I see :o

Then same with point b? two arcs?
with the same width of the compass ( a little bit wider compare to it is from the first step) , point at B draw 2 arcs as you do at point A |dw:1402455166894:dw| they will cut the arcs from A at E ( above ) and F ( below)
