Alison wants to construct the perpendicular bisector of MN¯¯¯¯¯¯¯.

 

What should Alison do for her first step?

 

Place the point of the compass on point M and draw an arc, using a width for the opening of the compass that is equal to12MN​ .

Place the point of the compass on point M and draw an arc, using a width for the opening of the compass that is greater than 12MN.

 

Use the straightedge to draw a line that intersects MN¯¯¯¯¯¯¯ at a point between M and N.

 

Place the point of the compass on point M and draw an arc, using a width for the opening of the compass that is less than12MN.
