Question

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

Explanation:

The image shows the first arc (centered at A) for segment bisection. The standard compass/string bisection method requires drawing a matching arc centered at B with the same string length, intersecting the first arc at two points.

Answer:

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