## acute angle

### An acute angle is a type of angle that measures less than 90 degrees

An acute angle is a type of angle that measures less than 90 degrees. In other words, it is an angle that is smaller than a right angle. Acute angles are commonly found in everyday situations, such as the angle formed by the hands of a clock at a certain time or the angle created when two lines intersect and form a “V” shape.

To visualize an acute angle, imagine a right angle (90 degrees) and then imagine further closing that angle until it becomes smaller than 90 degrees. Examples of acute angles include a 30-degree angle, a 60-degree angle, or a 75-degree angle. Acute angles are typically associated with sharp or slender shapes.

It is important to note that acute angles are always positive and never negative or zero. They are an essential concept in geometry and are used to classify and measure angles in various geometric shapes and constructions. In addition, acute angles have properties that distinguish them from other types of angles, such as obtuse angles (measuring more than 90 degrees) and right angles.
