What Are Acute Angles and Why Do They Matter in Geometry?

Acute angles are angles that are smaller than 90 degrees.

These angles are important because they help us understand shapes and how they work.

Some Examples of Acute Angles:

• In a triangle, you might see angles like 30 degrees, 60 degrees, and 90 degrees. The angles that are 30 degrees and 60 degrees are acute.
• You can also find acute angles in real life! For example, when the hands of a clock point at 2:00, they form an acute angle.

Key Features of Acute Angles:

• They are always less than 90 degrees.
• They are crucial for creating and figuring out other shapes.

Knowing about acute angles is the first step to learning about other types of angles. These include right angles (which are exactly 90 degrees), obtuse angles (which are between 90 degrees and 180 degrees), and reflex angles (which are between 180 degrees and 360 degrees).
