Final answer:
An angle that measures less than 90 degrees is classified as an acute angle, not an obtuse angle. Therefore, the statement that an angle less than 90 degrees is obtuse, is false.
Step-by-step explanation:
The statement in question is False. In the field of geometry, an angle that measures less than 90 degrees is not classified as an obtuse angle but as an acute angle. An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees. So, if ∠m < 90°, it would be an acute angle, not an obtuse angle.
