Scale Ruler on a Light Plot
How to use a scale ruler to add dimensions to a light plot.
Here's the worksheet I created for the exercise.
Here's the paper version of the Scale Rulers. When you print these out, be sure you have the print output set to No Scaling. The pdf needs to print full size to be in the proper scale. I suggest you still check it with an actual ruler. Also, if you make copies, double check those as well. I've had copiers enlarge/reduce by just 1-3% and it knocks everything off.
Thanks for visiting.
