Entering curves in using traverse tool.

While trying to plot these curves using the traverse tool I found this surveyor did not include a radial bearing or chord bearing specifically for the curves, like I see in other surveys.  I assumed then that the previous bearing would be the tangent bearing or potentially the radial bearing?  However when I plotted them nothing worked.  Also inputting the delta angle doesn't allow an arc length and therefore doesn't display correctly either.  What am I missing?  I understand I could just trace the georeferenced survey in this, but I really wan't to understand how to map a curve where the direction isn't given and the previous direction bearing isn't the proper direction either.

hi Dave,

no radial bearing as a note anywhere on that map? for the non-tangent curve option here: https://pro.arcgis.com/en/pro-app/latest/help/editing/enter-a-traverse.htm

maybe they put it in the legal description on the details page/section of that map

can you pull that [Record] deed/map for comparison?

Thanks for replying, these are the related documents (which take quite a while to find).  Also the legal description didn't have any bearing information just the same delta angle.  My concern is that the directions I found from these also don't give a curve that is correct when I use them in the traverse tool.  I come across this quite a bit when working with surveys.  So really I just want to figure out if there is a process to input curves if you only have the radius, arc length (length), and delta angle.
