Question

the numbered list gives instructions to bisect a line segment, but the steps are out of order. 1. use a straightedge or ruler to draw a straight line from the point where the arcs cross above the line segment to the point where the arcs cross below. 2. adjust the compass so that it is just a bit larger than half of the length of the line segment. 3. use the compass to draw arcs above and below the line segment. 4. place the pointed end of a compass at one of the terminal points of the line segment. 5. without changing the compass width, place the point at the other terminal point, and draw arcs above and below the line segment. if the line segment is already given, which is the correct order of the remaining steps to bisect the line segment? o 1, 3, 2, 4, 5 o 3, 5, 1, 4, 2 o 4, 2, 3, 5, 1 o 5, 4, 3, 2, 1

Explanation:

首先要将圆规针尖放在线段一个端点（4），然后调整圆规使其略大于线段长度一半（2），接着用圆规在线段上下画弧（3），不改变圆规宽度，将针尖放在另一个端点并在线段上下画弧（5），最后用直尺连接弧的交点（1）。

Answer:

C. 4, 2, 3, 5, 1
