I use these note shells so I can get through more problems during a class period. I do the first example with them and then there is a similar example for them to complete as group or individual work. This worksheet is designed to have them discover different types of word problems that require them to construct a right triangle in their drawing. It includes coordinates, directional problems, and square or rectangular diagonal problems. These problems also have a mix of a missing hypotenuese or leg. I use this as a second day of pythagorean theorem.
