What is the correct way to align a protractor when measuring an angle?

• Align the base with the vertex

• None of the above

• Align the center with the vertex

• Align the zero degree mark with the vertex

What does a measurement of 120 degrees indicate about an angle?

• It is a reflex angle

• It is an acute angle

• It is a right angle

• It is an obtuse angle

How do you determine the correct measurement when two numbers appear during measurement?

• Choose the smaller number

• Choose the larger number

• Choose any number

• Estimate the angle first

What is the purpose of drawing a dot at 60 degrees when using a protractor?

• To indicate the end of the angle
