When constructing inscribed polygons and parallel lines, how are the steps different?

a.) a protractor is used to take measurements.
b.) four right angles are created.
c.) a compass is used to copy an angle.
d.) there are no differences.

The correct answer is:

C) a compass is used to copy an angle.

Explanation:

When constructing parallel lines through a given point and a line:

Draw an arc from the point intersecting the line in two points.

Set the compass to a little over half of the distance between the points.

Draw an arc from each of these two points on the line (if the given point we start with is above the line, draw this arc below; if the given point is below the line, draw this arc below).

These arcs will intersect. Draw a point at their intersection.

Draw a line from our initial given point to this point.

Decrease the length of the width of your compass. Draw an arc from the original given point that intersects this new line in two points (one above, one below).

Widen the compass and draw an arc from both of these two points out from the initial given point.

These two arcs will connect; draw a point at their intersection. Draw a line from this point to the original given point.
