Answer 2

Brandon uses the following steps to construct a perpendicular line through a point C on a line segment. He first draws two arcs from point C intersecting the line segment in points A and B. The next four steps are listed below.

Step 1: Using the same compass width draw two more arcs from point C, one above and the other below the line.
Step 2: Without changing the compass width draw two arcs from point B above and below the line segment.
Step 3: Label the point of intersection of the arcs above the line segment as M and below the line as N.
Step 4: Using a straightedge, join point M and point N.

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 Brandon.

Answer 3

I'd be glad to check any work that you share, if you show how you got your answers.

Answer 4

Okay :)

Answer 5

So, because i'm better at visual understanding I had to draw out my steps, and I did so then when i drew it all out I thought that step 1 was incorrect and I just wanna know if that is right or wrong :D

Answer 6

The reason why I thought step 1 was the first incorrect step is because I think he should've opened his compass a little bit wider and drew the arc from point A and not C

Answer 7

Really, I think a visual approach is the best one here in any case. I am much handicapped in not being able to see your actual work. While I imagine it could be a lot of trouble for you, I'd suggest that you take a cell phone photo of your work on paper and share the image here. Use Attach File.

To be honest, I'm getting off the Internet in just a few minutes, so you may either need to wait until tomorrow to meet up with me online again, or wait for another person to answer.

Answer 8

I'll just wait until tomorrow

I know how to get it to cross from point C in my problem, I'm just not sure how to explain everything for part 2 and 3 @Hero
