1. this diagram was created by starting with points a and b and using only straightedge and compass to construct the rest. all steps of the construction are visible. describe precisely the straightedge and compass moves required to construct the line cd in this diagram.

Explanation:

Step1: Set compass width

Set the compass width to the distance between points A and B.

Step2: Draw circles

With the compass centered at A, draw a circle. Then, with the compass centered at B, draw another circle using the same width. The two circles intersect at two points (C and the other intersection point).

Step3: Draw line

Use the straightedge to draw a line connecting the two intersection - points of the circles. This line is CD.

Answer:

1. Set compass width to AB. 2. Draw circles centered at A and B. 3. Use straightedge to connect intersection - points of the circles to get line CD.
