Suzy is bisecting a line segment. What is the missing step?

1. Place the compass at one end of line segment.

2. Adjust the compass to slightly longer than half the line segment length.

3. Draw arcs above and below the segment.

4. ________

5. Place ruler where the arcs cross, and draw the line segment.

• Place a point on each arc.

• Keeping the same compass width, draw arcs from the other end of the segment.

• Adjusting the compass to a slightly longer width, draw arcs from the other end of the segment.

• Adjusting the compass to a slightly shorter width, draw arcs from the other end of the segment.

What is the first step in bisecting a line segment?

• Draw a perpendicular line

• Place the compass at one end of the segment

• Draw an arc from the midpoint

• Measure the segment

When copying an angle, what tool is essential?

• Protractor

• Compass

What is the correct sequence for bisecting a line segment?

• Draw a line, measure, draw arcs, connect points

• Place compass, adjust width, draw arcs, repeat from other end, connect intersections

• Draw a circle, draw a line, measure, connect points

• Place ruler, draw line, measure, draw arcs

What is the main difference between copying a segment and copying an angle?

• Copying a segment uses a protractor

• Copying an angle uses a compass and straightedge

• Copying a segment involves measuring length, copying an angle involves measuring rotation

• Copying an angle uses only a ruler
