Assume the line AB←→ and a point P, not on the line have already been constructed. What is the first step to construct a parallel line passing through the point P? (1 point)
1. Use a compass to draw an arc centered at point P that intersects AB←→, and label the intersection points C and D.
2. Use a compass to draw an arc centered at point B that intersects the AB←→, and label the intersection point C.
3. Use a compass to draw an arc centered at point a that intersects AB←→, and label the intersection point C.
4. Construct another point Q different from point P that is not on the line.
