# Acute angle

## Acute angle – An angle that is less than 90° (a sharp angle).

**A cute** (acute) animal is always small (less than 90°), but watch out! It has very **sharp** teeth (a sharp angle).

**Example 1**

An angle less than 90° is described as acute.

**Example 2**

Although these two angles are different, they are both less than 90° and are therefore both acute angles.

**Example 3**

You may only just be able to see an acute angle.
