Question

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

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 Brandon.

Answer 2

its 1.263

Answer 3

what?

Answer 4

im lying im srry that wasnt me typing

Answer 5

ok

Answer 6

The step used to take A is omit.
The Rhombus CMBN has two diagonals CB and MN Orthodiagonal together because CM = CN=BM=BN.
the compass works for that because when we don't change the its with it makes the same arc and the same length

Answer 7

that fact help you draw the llrhollmbus square or divide the segmant line and so on which have to be the same length

Answer 8

Could you put that first part in english

Answer 9

alright hold on a sec i'lll try

Answer 10

thnx

Answer 11

Step 1: The width of the compass must be increased... okay?

Answer 12

got it

Answer 13

Arcs above from the left and right will only intersect at point C NOT above and below the line and will NOT make 2 points M and N if the width is not changed. Understand?

Answer 14

yeah

Answer 15

Wait I think I get it, you said above the step to make A is omit so is that the right answer for step 1

Answer 16

The compass makes an arc of points that are equidistant from the pivot point. The perpendicular bisector of a line segment is a line composed of all points which are equidistant from the endpoints of the segment. The compass allows you to find 2 of those points M and N. Any line is determined by two points soo... the line drawn through M and N will contain all of those points and will be perpendicular bisector. I HOPE THIS HELPED!!!!!

Answer 17

It did, thnx a lot.

Answer 18

your welcome!!!!!!!!!!! do you need help with any more?

Answer 19

Nope, I'm good

Answer 20
