Alice is designing a book shelf. the segment lq represents the base of the book shelf. alice wants to construct a line to represent a rack passing through r and parallel to side lq. she uses a straightedge and compass to complete some steps of the construction, as shown below: which of these is likely to be her next step in constructing the rack parallel to lq? answer choices: place the compass at s and adjust its width to point p. without changing the width of the compass, fix the compass at p and draw an arc. without changing the width of the compass, place the compass at s or p and draw an arc similar to the one drawn. place the compass at n and adjust the width to a length that is greater than the length of segment ns.
