prabhsingh sent me a PM asking me for the template. I've already replied to him but realized that there could be more like him ... so ....

How to draw templates
What you will need
All You need is a regular 180 degree protector that you can find in school kid's compass box and few colored ball pens or pencils and some time!!
Here are the steps
On a blank sheet of a paper, plot x & y axis on paper such that intersect near lower LHS of page (I used landscape alignment, Portrait will work too).
Draw the axis with a darker ink (preferably red color ball pen).
Next, Place a protector such that its zero point (hole) coincides with X=0, Y= 0 and its straight edge is parallel to X Axis.
Next, Mark out points at 22.5, 45, and 67.5 degrees indicated by protector
Next, draw lines from X0Y0 to each of these points with any dark color such as black (basically anything other than red);
Nice thing about the Protector that I had used is that it had grooves at most important degrees, so you could actually draw a small line segment.
I do not remember seeing this kind of protectors during my school days.
Similarly, you can draw angles for 15, 30, and so on. Another common combination is 10, 20, 30.
WHY TO DO THIS
Best paper to use is Trace Paper. You can use this perfect sheets by holding it against a screen and verify the angles plotted by software. Key objective of Drawing on paper is to rule out inaccuracies that are caused by rectangular shape of charts. It is assumed that for perfect angles, "square is required"
