How to constructa angle of measure25.5 degree

Dear Student

1st draw a line AB and set centre of protector at point A and mark a point in between 25 and 26 (let assume point C)
Now join the line AC which is a line at 25.5 degree from AB.

But i think actual question is to draw angle 22.5 degree using compass.
For that we have to follow these steps
