angles there are whole new sets that can also be used to make that same congruent shape. Using that information‚ we were able to make an equation that calculates the total degrees in any polygon. These outside angles had no real connection to the shadow unit problem. More About Angles shows just how important angles are to all polygons‚ especially triangles. Angles are mostly what decide the shape of triangles. This activity was about grouping similar angles from a set of parallel line with another line
