## acute angle

### An acute angle is an angle that measures less than 90 degrees

An acute angle is an angle that measures less than 90 degrees. In other words, it is an angle that is smaller than a right angle.

To help visualize this, imagine a straight line. If you place two line segments with a common endpoint on this line, you create an angle. If the two line segments are very close to each other and make the shape of a “V,” the angle between them would be acute.

Acute angles can be found in various geometric shapes, such as triangles or parallelograms. For example, in a right-angled triangle, the two angles that are not the right angle are always acute.

Acute angles are an important concept in geometry and trigonometry. They are used to measure the inclination or slope of lines, calculate distances, and solve various mathematical problems.
