Acute Angle:
An acute angle is an angle whose measure is less than 90°. When we talk about angles, we are referring to the amount of turn between two lines that meet at a point. An acute angle is one that is smaller than a right angle (90°) and does not exceed 90°.

Characteristics of Acute Angles:
- An acute angle measures between 0° and 90°.
- It is sharper or smaller than a right angle.
- In geometry, acute angles are often represented by a small arc in between two lines.

Examples of Acute Angles:
- An angle of 30° is an acute angle.
- An angle of 85° is also an acute angle.

Importance of Acute Angles:
Understanding acute angles is essential in geometry and trigonometry as they are fundamental to various mathematical concepts. Acute angles are commonly found in shapes like triangles, where they play a crucial role in determining the type and properties of the triangle.
In conclusion, an acute angle is a fundamental concept in geometry that is defined by its measure being less than 90°. Understanding acute angles is important for various mathematical applications and forms the basis for more advanced geometric concepts.
