An architect plans to make a drawing of the room of a house. The segment LM represents the floor of the room. He wants to construct a line passing through Q and perpendicular to side LM to represent a wall of the room. He uses a straightedge and compass to complete some steps of the construction, as described:
A line segment LM is drawn.
Two arcs equidistant from L on line LM are drawn at points P and T.
A point Q is just above L.
A compass is fixed at point Q and is shown making an arc at T.
Which of these is likely to be his next step in constructing the perpendicular line?
A.) Fix the compass at L and draw an arc above the line.
B.) Without changing the width of the compass, place the compass at Q and draw an arc through L.
C.) Fix the compass at points P and T and draw arcs which intersect below the line.
D.) Without changing the width of the compass, place the compass at M and draw an arc.
