Question

select the correct answer. based on the construction shown, what is the next step when bisecting line segment ab using string? a. keep the string length and draw an arc centered at point b that crosses the other arc in two places. b. set the string length at point a and at the top of the arc. c. using a straightedge, draw a line perpendicular to segment ab so it crosses the arc in two places. d. set the string length between point a and where the arc crosses segment ab.

Explanation:

When bisecting a line - segment using string, after drawing an arc centered at one end - point (say A), the next step is to keep the same string length (radius) and draw an arc centered at the other end - point (B) such that the two arcs intersect at two points. These intersection points are then used to construct the perpendicular bisector of the line segment.

Answer:

A. Keep the string length and draw an arc centered at point B that crosses the other arc in two places.
