Rachel is drawing a square. She draws a circle with a compass setting of r units. Which of the following is the next thing Rache
natka813 [3]

Answer:

<em><u /></em>

  • <em><u>A. Draw a diameter of the circle. </u></em>

Explanation:

To<em> draw a square</em> you can <em>draw a circle</em> with a <em>compass</em> and then construct the inscribed square.

You can construct an inscribed square with a compass and a straightedge.

The <u>first step</u> is to draw the circle.

The <u>next</u> step is to <em>draw a diameter</em> (any line that passes through the center of the circle, which you marked when drew the circle). Hence, this is the correct answer to the queston, and it is described by the choice A.

After that, you will be able to draw the perpendicular bisector of the diameter. The two diameters drawn will mark four equidistant points on the circle which will be the four vertices of your square.

Finally, you just must join the adjacent vertices with the straightedge.
