Measuring Angles

What is the difference between acute, obtuse, and right angles?

• Acute angles are between 90 and 180 degrees

• Right angles are between 90 and 180 degrees

• Acute angles are less than 90 degrees, obtuse angles are between 90 and 180 degrees, and right angles are exactly 90 degrees.

• Obtuse angles are less than 90 degrees
