Ammar is constructing an angle congruent to ∠mnp ∠ m n p . with his straightedge, he draws and labels de−→− d e → . he places the compass point on point n and draws an arc that intersects nm−→− n m → and np−→− n p → . he labels the point where the arc intersects nm−→− n m → as point q and the point where the arc intersects np−→− n p → as point r. without changing the compass opening, he puts the compass point on point d and draws a long arc that intersects de−→− d e → . he labels the point of intersection as point f. what is ammar's next step? without changing the compass opening, put the compass point on point d and draw an arc. open the compass so that the compass point is on point q and the pencil point is on point r. then put the compass point on point f and draw an arc. open the compass so that the compass point is on point q and the pencil point is on point r. then put the compass point on point
