Question

Meng is constructing the perpendicular bisector of MN¯¯¯¯¯¯¯ . She placed the compass point on M, opened the compass to more than half the length of segment, and drew an arc above point M.

Which move would be a correct next step to take?

A. Keep the same compass opening, place the compass point on the arc, and draw an arc that intersects point N.

B. Keep the same compass opening, place the compass point on the arc, and draw an arc that intersects point M.

C. Widen the compass opening, place the compass point back on point M, and draw an arc below MN¯¯¯¯¯¯¯ .

D. Keep the same compass opening, place the compass point back on point M, and draw an arc below MN¯¯¯¯¯¯¯ .

Answer 1

@dude

Answer 2

any idea ?

Answer 3

this is the rule to constract a perpendicular bisector of a line segment AB

open the compass more than half of the distance between A and B, and scribe arcs of the same radius centered at A and B.

using this how you think what choice may be right ?

Answer 4

B if i'm correct

Answer 5

sorry i m not sure

Answer 6

the text of your exercise said that ,, opened the compass to more than half the length of segment, and drew an arc above point M.
