Marcello is constructing the perpendicular bisector of AB¯¯¯¯¯. He has already constructed arcs as shown.



What should Marcello do for his next step?

A. Use the straightedge to draw AX←→ and AY←→.

B. Use the straightedge to draw a line through points X and Y.

C. Place the point of the compass on point X and draw an arc, using AX as the width for the opening of the compass.

D. Place the point of the compass on point X and draw an arc, using AY as the width for the opening of the compass.

Answer 1

Your correct answer would be B! :D

Answer 2

To get the perpendicular of a line, a compass is needed to draw 2 arcs from the 2 ends of the line.

The radius of the arc must be more than half the length of the line.

By drawing a line through the 2 intersections of the arcs, you will get the perpendicular of the line.

Answer is B.
