Question

Which of the following is being constructed in the image?

A) a line perpendicular to a given lune through a point on the line
B) a line segment that is congruent to a given line segment
C) a perpendicular bisector of a line segment
D) a line parallel to a given line through a point not on the line

Answer 1

The answer is C, a perpedicular bisector. The distances of the mark along the given line are equidistance. Where the x is located, where the two dashes would intersect is where a 90 degre angle to the line would pass through. 

Answer 2

A) a line perpendicular to a given line through a point on the line.

Explanation:

Perpendicular means at a 90 degree angle.

As we can see, the arcs are crossing on a dotted line that is going through a point, and is perpendicular to the line the point is on.
