HW Week 2

Suppose we wish to construct angle EFG congruent to angle DBC using a compass and straightedge. Which step would be correct to do first?

• Place the compass point at B
• Place the compass point at C
• Place the straightedge along A and C
• Place the straightedge along C and D

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

What is this?

• Compass
• Circle creator
• Pencil swingy-thing
• Arc maker

What is being represented in the image?

• Radius

• Diameter

• Inscribed Angle

• Secant

The radius is ____ the diameter

• half

• double

• one third of

• bigger than
