How do you construct a 135-degree angle?

Answer

A 135 degree angle is a specific geometric, obtuse angle. A protractor is undoubtedly the best way to correctly draw the angle, however if one can not be attained, other methods can be used. One of the best ways is finding an object that has an obtuse angle, or has the supplement of an acute angle. This will allow you to trace a rough guess of the angle, if you have good memory as to what a 135 degree angle looks like.
