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.

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.
