Angles on a Protractor

What is the measure of a 160-degree angle?

• A 160-degree angle is a right angle.

• A 160-degree angle is an acute angle.

• A 160-degree angle is an obtuse angle that is close to a straight angle.

• A 160-degree angle is a reflex angle.

How do you read a protractor?

• Align the baseline of the protractor with one side of the angle and read the measurement where the other side crosses the numbered scale.

• Hold the protractor vertically and measure the angle from the top.

• Use the protractor to draw angles instead of measuring them.

• Place the protractor on the table and look at the angle from above.

What is the difference between acute and obtuse angles?

• Acute angles are greater than 90 degrees, while obtuse angles are less than 90 degrees.

• Acute angles are less than 90 degrees, while obtuse angles are more than 90 degrees but less than 180 degrees.

• Acute angles are exactly 90 degrees, while obtuse angles are more than 180 degrees.

• Acute angles and obtuse angles are the same, both being less than 180 degrees.

What is an obtuse angle?
