Triangles are classified into acute and obtuse angles. In geometry, an acute angle is less than 90° and an obtuse angle is greater than 90° but less than 180°.

As a result, 78 degrees represents an acute angle.

An angle that measures 78 degrees is an acute angle. Acute angles are those that measure less than 90 degrees.
