No, an acute turn cannot equal a straight angle. Acute angles are always less than 90°, while a straight angle is exactly 180°. Since acute angles are smaller, they can never become equal to straight angles.

Class 5 Mathematics Maths-Mela Chapter 3 Angles as Turns question answer
An acute angle is defined as being less than 90°. A straight angle, on the other hand, measures exactly 180°. Since an acute angle is always smaller than a right angle and a straight angle is double a right angle, there is no possibility for an acute turn to equal a straight angle. The two types are completely different in size and measurement.
