Question

Joe uses the following steps to construct a perpendicular line through a point C on a line segment:

Step 1: From point C, draw an arc intersecting the line segment in points A and B.
Step 2: Use a straightedge to draw an arc from point A, one above and the other below the line.
Step 3: Without changing the compass width, 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 Q and below the line as R.
Step 5: Using a straightedge, join points Q and R.

Answer 1

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 Joe.

Answer 2

My answer:
Part A: Step 2 is the first incorrect step
Part B: Because it tells you to draw an arc with a straightedge and you can't draw curves with straightedges.
Part C:

Answer 3

This is the last one I have :P

Answer 4

@perl, can you verify if I'm right?

Answer 5

Straightedges are not used to draw arcs.

Answer 6

Its cool, I'm done, I submitted it :)
