What is an acute angle?

An angle equal to 90 degrees
An angle with a measure less than 90 degrees
An angle greater than 90 degrees but less than 180 degrees
An angle with no measurable size

The correct answer is: An angle with a measure less than 90 degrees

An acute angle is defined as an angle that measures less than 90 degrees. This means that acute angles are sharp and smaller than a right angle, which measures exactly 90 degrees. Understanding acute angles is fundamental in geometry, as they are commonly encountered in various shapes and designs. This definition also highlights the contrast with other types of angles: right angles (90 degrees, which is not acute) and obtuse angles (greater than 90 degrees but less than 180 degrees). Therefore, the correct choice reflects the precise definition of acute angles in geometric terms.
