On the screen, we see an angle formed by three points A, O and B. We can change the size of this angle by using the slide bar. Now let us change the angle from 0 degrees to 360 degrees and observe how its shape changes.
1. What difference do you observe when α=0˚, 0˚<α<90˚, α=90˚, 90˚<α<180˚, α=180˚, 180˚<α<360˚ and α=360˚?
2. Do you know the names of the different angles we saw when we changed the sizes as described above?
