One way is to use a protractor. There are others
With a straight edge and a protractor is the simplest way.
To measure an acute or obtuse angle:Put the cross-hairs at the centre of the base line of the protractor on the point of the angle;Align one zero on one arm of the angle (keeping the cross-hairs in place) with the circular part of the protractor over the other arm;Read off the angle of the other arm with the scale that starts at 0o on the first arm.To measure a reflex angle:Measure the angle (of the small angle) between the arms as above;Subtract the found angle from 360o.Note:The base line of the protractor is the straight line marked on the protractor that runs from 0o to 180o; half way along this line will be a perpendicular line towards the 90o mark which may touch or cross the base line - this point is the "cross-hairs".To draw a given angle:To draw an acute or obtuse angle:Draw one arm of the angle;Put the cross-hairs at the centre of the base line of the protractor on the end of the arm that forms the point of the angle;Align one zero on the drawn arm of the angle (keeping the cross-hairs in place) with the circular part of the protractor where the other arm should go;Mark the angle of the other arm with the scale that starts at 0o on the first arm.Draw in the other arm;Optional: mark the angle (between the lines) with a small arc near the point.To draw a reflex angle:Subtract the angle from 360oDraw as above; except the angle is marked with a small arc round the outside of the arms (instead of between them).
There isn't a formula for determining the degrees of a simple acute angle. The only way is with a protractor or estimate.
you can only draw an reflex angle if you have a circular protractorthere is also a way with a normal protractor you can rotate your protractor and there you can now make ur Reflex angleRememberyou should minus 1 degree
