1. 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. Use a compass to draw an arc centered at point B that intersects the AB, and label the intersection point C.
2. Construct another point Q different from point P that is not on the line.
3. Use a compass to draw an arc centered at point a that intersects AB, and label the intersection point C.
4. Use a compass to draw an arc centered at point P that intersects AB, and label the intersection points C and D.
2. In the given image, what is the next step for constructing a parallel line passing through point P?
1. With the compass opened to less than half of CD, draw arcs centered at C and D and label the point of intersection of the arcs E.
2. Decrease the size of the compass and draw one arc centered at point C, a second arc centered at point D, and label the point of intersection between the two arcs E.
3. Increase the size of the compass and draw one arc centered at point A, a second arc centered at point B, and label the point of intersection between the two arcs E.
4. With the compass opened to at least half of CD, draw arcs centered at C and D and label the point of intersection of the arcs E.
