What is the first step in the construction of a line perpendicular to AB←→ 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 AB←→. B.) Place the compass needle at any point on AB←→, and set the compass width to M. C.) Draw a line from point M passing through AB←→, and mark the point of intersection. D.) Place the compass needle at any two points on AB←→, and draw two arcs through M.
