Measure angle between two separate lines

Hi
I would like to measure the angle between two separate lines with ImageJ. Can someone recommend a plugin please

Best

Hi @Mathew
thank you so much
i am very new to ImageJ, i am also very new to coding and not comfortable with the open source software.
how can i save the Macro u sent?

Copy the macro and paste it in:
plugins -> New -> macro
then
->macro -> run

Thank you @Mathew
I run the macro but still not sure how to measure the angle between two separate lines

Example:

run("AuPbSn 40 (56K)");
makeLine(86, 154, 364, 58);
roiManager("Add");
//setTool("line");
makeLine(209, 184, 394, 223);
roiManager("Add");
roiManager("Select", 0);
// run Macro
roiManager("Select", 1);
// run Macro

(follow line by line)
The result is in the “results” window

Continuing the discussion from Measure angle between two separate lines:

Hi Mathew.

I m sure for you is very easy but I am stuck.
How can I measure the the angle between 2 independent lines ??
And obvious how to maintain the 2 drawn lines on the image opened in ImageJ???

I tried to follow understand what you have wrote above, but no luck in understanding.
How to make a macro/plugin and where to add the macro/plugin .

If is ok with you , can you post here step by step what I need to do to. I need it for a big research paper.

Thank You in advance
