What is the first step in the construction of a line perpendicular to and passing through an external point M? Assume that the construction uses only a compass and a straightedge. A.Place the compass needle on M and, keeping the compass width the same, draw two arcs that intersect .B. Place the compass needle at any point on , and set the compass width to M. C.Draw a line from point M passing through , and mark the point of intersection. D.Place the compass needle at any two points on , and draw two arcs through M.
