8-27: Basic Construction

The given diagram is what kind of construction?

• Perpendicular bisector

• Congruent angles

• Angle bisector

• Congruent line segments

When copying line segment AB using a straight edge and a compass, the compass should be used to:

• Draw an arc above point A

• Measure the length of segment AB

• Draw an arc between point A and point B

• Measure half the length of line segment AB

What was duplicated?

• line

• line segment

• ray

• angle

The drawing shows the arcs used to construct...what?

• a bisector of a given line

• a bisector of a given angle

• a perpendicular of a given line at a point on the line

• an angle congruent to a given angle
