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:
The point at which two rays join are called Vertex
For the given image, point O is the vertex of the angle
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
