Answer:

No

Explanation:

Acute angles are angles that measure less than 90 degrees. Obtuse angles are angles that measure more than 90 degrees. However, there are other types of angles. Take a right angle for example. It measures exactly 90 degrees, therefore it is neither obtuse or acute. So, Anton's definition cannot be valid - there are still other angles that are not obtuse that don't qualify as acute, either.
