What is the first step in constructing a perpendicular bisector?

• Measure the line segment

• Label the endpoints

• Set the compass point on the line segment

• Draw a straight line

How do you determine if two lines are parallel using alternate interior angles?

• The angles are complementary

• The angles are adjacent

• The angles are congruent
