When constructing an inscribed polygon with a compass and straightedge, how should you start the construction? ?

a- use a protractor to measure the original circle into four equal parts.
b- use a ruler to find the length of the diameter and then make an arc above it.
c- open the compass to the width of the circle and use that as a guide
d- place a point on your paper and then use a compass to construct a circle.

step-by-step explanation:

just id the test.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
