help ma pleaseWhat are the steps for using a compass and straightedge to construct a line through point A that is parallel to line j?A horizontal line j and a point A are drawn. The point A is below the horizontal line j.Drag the steps and drop them in order from start to finish.Place the point of the compass on point Q and open it to width QR .Use the straightedge to draw a line k that passes through A and intersects line j. Label the point of intersection as point P.Use the straightedge to draw AB←→.Without changing the width of the compass opening, place the point of the compass on point A and draw an arc that intersects line k. Label the intersection as point S.With the compass opening set to width QR , place the point of the compass on point S and draw an arc that intersects the arc that was drawn from point A. Label the intersection of the arcs as point B.Place the point of the compass on point P and draw an arc that intersects lines j and k. Label the intersections as points Q and R.
