• 180 degrees

What is the difference between a right angle and an acute angle?

• A right angle measures exactly 90 degrees, while an acute angle measures less than 90 degrees.

• A right angle measures less than 90 degrees, while an acute angle measures exactly 90 degrees.

• A right angle measures 180 degrees, while an acute angle measures less than 180 degrees.

• A right angle and an acute angle both measure 90 degrees.

Can an angle be both acute and obtuse?

• Yes, an angle can be both acute and obtuse.

• No, an angle cannot be both acute and obtuse; they are mutually exclusive categories.

• An angle can be acute in one context and obtuse in another.

• It depends on the measurement of the angle.

What is an obtuse angle?

• An angle that is exactly 90 degrees.

• An angle that is less than 90 degrees.

• An angle that is more than 90 degrees.

• An angle that is equal to 180 degrees.

What is a reflex angle?

• An angle that measures exactly 180 degrees.

• An angle that measures less than 90 degrees.

• An angle that measures more than 180 degrees but less than 360 degrees.

• An angle that measures exactly 360 degrees.
