Join line segments with similar bearing

[SherilynWilliams-Stroud]

All the faults on my imported map are composed of small line segments. I'd like to combine the line segments that are connected and which have a similar bearing into single larger segments so that I can get the #fault trace lengths. Is there a way to do that?

Ok. Thanks for your help, anyway. The data source is Oklahoma Geological Survey. I also have USGS data, but the faults in the USGS data seem not to be as segmented, meaning most of the fault lines on the map are one polyline, not a bunch of short polylines strung together.
