Finding the Distance Revamped!

"Finding the Distance" foldable was requested in the form of a pdf.
Finding the Distance

I have typed it up and uploaded it as a word document (editable) and as a pdf. An answer key has been uploaded also. As always, printing can be tricky. I print "two sided along the short edge". After printed, you'll notice a dotted line along one short edge. Cut along the dotted line so that the foldable will fold up nicely.

First unfold reveals methods for distance off a slanted line along with using method 1. 

Second unfold reveals the use of method 2. 
The order of the methods did not hold a significance initially. I now teach the use of the Pythagorean Theorem first to bridge a connection the the distance formula.
