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?


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

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

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

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

Answer 1

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

Explanation:

Answer 2

Answer: She should keep the same compass opening, place the compass point back on point M, and draw an arc below the line segment MN.

Explanation:

According to the rule of construction of perpendicular bisector, she should draw an arc both side of line segment without changing the opening of the compass.

So, her next step would be to take the third option, i.e. She should keep the same compass opening, place the compass point back on point M, and draw an arc below the line segment MN.
