Q:

Math... ಠ_ಠ .......................................................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.

Accepted Solution

A:
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.
