# Working With Angles Worksheets

How to Become Comfortable Working with Angles To work with angles and properly understand them, their nature, and how they work is tricky business at first. The most important thing related to angles is to construct them with precision. Angles are usually drawn to complete a certain shape. If any angle is not drawn perfectly and with extreme accuracy, the shape can go wrong. So, an angle should be drawn to precision. There are many ways of drawing an angle with precision. Some use protractors will others are comfortable with the conventional method of drawing an angle by a compass. Then comes its calculation. Angles can be calculated using a protractor, but in complex shapes, it is often difficult to do that using a protractor. For that, mathematical calculations are required. For example, a straight line is always 180 degrees. If an angle of 40 degrees is subtended at one end of that straight line, the angle made opposite to that 40 degrees is easy to calculate. You just need to subtract 180 by 40. This is how the angle calculation is done.
