J.L.

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. Part A: Which is the first incorrect st

    Part 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.

    Problem is, that is how I would construct perpendicular lines. :/

    same here...there needs to be something wrong though Is it that she drew an arc above the line when she was supposed to do it below?

    I think perpendicular line 'through' a point suggests you need both though

    Actually you would need both anyway as you wouldn't be able to align your ruler without both points.

    You already have point C above the line segment so there is no need for another point above the line segment. So I think it might be that.

    This is my answer: Part A: The first incorrect step is that she drew an arc above the line segment (Step 2). Part B: Step 2 is the first incorrect step because point C is already above the line segment so there is no need to create another point above the line segment, only below it. Part C: A compass works for the construction because you are able to draw arcs of same lengths from the points created on the line segment.

    Was there a diagram, as I don't see where it specifies where C is. I assumed it was on the line.

    I'm pretty sure it was above the line...I'm good now thanks
