Our national flag is the symbol of our independence and sovereignty. It is rectangular in size. There is a red circle in the midst of green. The ratio of the length and width of the is 10:6. Red and green colors are used in it. They symbolize that the martyrs who laid down their lives for the freedom of our country are evergreen. Late artist Kamrul Hasan designed it. It is hoisted of different national occasions. It was first raised on the premises of the University of Dhaka on the 2nd March, 1971. The design of that flag was a little bit different earlier. Our national flag represents our national identity. To show due respect and honour to our national flag is our bounden duty.
