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.

Place the compass needle on M and, keeping the compass width the same, draw two arcs that intersect AB←→.

Place the compass needle at any point on AB←→, and set the compass width to M.

Draw a line from point M passing through AB←→, and mark the point of intersection.

Place the compass needle at any two points on AB←→, and draw two arcs through M.
