How to draw an angular arc after measuring the angle between two crossing lines?

Dear Community,

for a scientific work I need to measure the angle between two crossing lines. Measuring so far is not a problem, but I would like to draw the angular arc into my image, so that the measured angle is visible. Does anybody know how I can do this, or if there is any plugin/macro to do that?

To acomplish this needs some work because this task has no direct relation to image analysis and processing.
Using the angle tool may give you something like:
Step-1
Store this selection in the ROI-manager.
Draw a circular selection with its center at the apex:
Step-2
Store this selection in the ROI-manager.
Now select both entries in the ROI-manager and chose “AND” from its “More”-menu.
Store the result in the ROI-manager which gives you:
Step-3
