Question

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 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 equal to 12MN​ .
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 than 12MN

Answer 1

What should Alison do for her first step ? She should learn to intersect the bisector of the intersector of mn such that mn should be the intersection of mn to nm so that no 2 intersections should intersect each other's bisector of mn to intersect of mn.
