Marcello is constructing the perpendicular bisector of AB¯¯¯¯¯. He has already constructed arcs as shown.What should Marcello do for his next step?a) Place the point of the compass on point X and draw an arc, using AY as the width for the opening of the compass.b) Use the straightedge to draw a line through points X and Y.c) Use the straightedge to draw AX←→ and AY←→.d) Place the point of the compass on point X and draw an arc, using AX as the width for the opening of the compass.

Answer: "Use the straightedge to draw a line through points X and Y." is the right answer.
Step-by-step explanation:To perpendicular bisector of line segment AB. There are following steps:1) Draw arcs from points A and B on the both sides of AB.2) Name the intersection points as X and Y.3) Use the straightedge to draw a line through points X and Y. 4) Name the point as O hence we have construct perpendicular bisector XY of AB which bisects at O.
