Question

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 1

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

Explanation:

took the test and got it correct

Answer 2

Answer: "Use the straightedge to draw a line through points X and Y." is the right answer.

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.
