Constructions

The drawing shows a compass and straight edge construction of...what?

• the bisector of a given angle

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

• a perpendicular to a given line from a point NOT on the line

• an angle congruent to a given angle

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 is being constructed in the figure?

• the perpendicular bisector of line m

• the line perpendicular to line m through a point on the line

• the line parallel to line m through a point NOT on the line

• an angle that has line m as its bisector

When constructing a line parallel to a given line, you will be
