Angle whose measurement is less than 90 degrees is an** Acute angle**.

If you want to draw acute angle, you can draw it from** range 0 to 89 degree**.

Below are some examples of Acute Angle:

**Parts of Acute Angle**

The angle is made up of two rays joining at angle less than 90 degree.

Some important parts of an angle are:

**(a) Vertex**

The point at which two rays join are called Vertex

For the given image, point O is the vertex of the angle

**(b) Arms**

The two rays forming the angle is known as Arms

In the below angle OA & OB are the two arms

**Draw Acute angle using Protractor**

For drawing acute angle, do the following steps:

**(a)** Take a sheet of paper and draw horizontal line

This is one arm of the angle

**(b)** Take protractor and place its center at point O as shown in below figure

To draw acute angle you have range of options from 0 to 89 degree as shown below

**(c)** Let us draw an angle of 50 degree

Draw a point at 50 degree protractor and name it Point B

**(d)** Remove the protractor and join OB with straight line

We get Angle AOB = 50 degree.

You can choose to draw acute angle of any measurement or your choice.

Just make sure the angle measurement is between 0 and 90 degree

**Acute Angle in Real Life**

Some of the real objects form acute angle with its body

**(a)** Acute Angle by Pizza Slice

**(b)** Acute Angle by Scissor

**(c)** Acute Angle by Clock
