What is the first step in copying a line segment?

• Measuring the segment with a ruler

• Designating a point

• Drawing a circle

• Drawing an arc

How do you ensure the copied segment is the same length as the original?

• By drawing a parallel line

• By keeping the compass length unchanged

• By using a protractor

• By measuring with a ruler

What is the first step in copying an angle?

• Drawing a straight line

• Designating a vertex

• Measuring the angle with a protractor

• Drawing a circle
