An acute angle is an angle whose measure is greater than 0 degrees and less than 90 degrees. In other words, an acute angle is an angle that is smaller than a right angle.

This type of angle is an acute angle

The other side’s large angle is called Reflex Angle.

Look below Angles’ images. These all are acute angles:

### Definition of Acute Angle

If an angle is 49° angle that is called an Acute angle but if another side is 311° angle is called a reflex angle.

### Real-life examples of acute angles are:

#### 1. pizza slices

If you slice a **pizza 5,6 or more slices**, then each slice of pizza will make an acute angle.

#### 2. Wall clock

**The wall clock** is another example of an acute angle. It makes acute angles at numerous hours of the day. **For example, **10 o’clock.
