Question

select the correct answer from the drop - down menu. the diagram shows a stage in the construction of a line perpendicular to $overline{gh}$ through point $a$. the next step in this construction is

Explanation:

To construct a line perpendicular to a given line through a point on it, after marking two points (G and H) equidistant from the given point A on the line, the next step is to keep the same compass - width (the distance between A and either G or H) and draw an arc centered at H that crosses the previous arc. This helps in finding the points to draw the perpendicular line.

Answer:

to keep the same compass width and draw an arc centered at H crossing the previous arc in the image
