Which term describes an angle less than 90 degrees?

Explanation:
An angle smaller than a right angle is called an acute angle. In geometry, angles are grouped by size: acute means less than 90 degrees, right means exactly 90, and obtuse means more than 90. So when an angle is less than 90 degrees, you describe it as acute. The other terms refer to different ideas—survey is about measuring land, plot can mean land or a graph, and transformation is a change applied to a figure. That’s why the best term for an angle under 90 degrees is acute angle.
