I've been working my way through this book armed with MS Paint. It seemed a nice way to represent the simple diagrams without too much work, given than the images on the scans aren't always hugely clear.

I'm uploading the diagrams onto Wikimedia Commons tagged with Byrne's Euclid https://commons.wikimedia.org/wiki/Category:Byrne%27s_Euclid. There are also necessary illustrations like the decorated drop capitals.

In general, I'm just using colours black, red, yellow, and indigo on MS Paint to match the colours in the book. My process for each page is to copy the main diagram as accurately as possible, and pull out the angles and parts of it that are used on their own in the text. It took me a while to decide on a standard format, but now each diagram is named Byrne [page number] [description of diagram] e.g. Byrne 64 red angle.

There are a few really useful images that get used a lot and can be reused: These should all be scaled to 50px for consistency, e.g. (File:Byrne 35 diagram 5.png|50px). There are also dotted lines of different colours, and partially solid, partially dotted lines.

 * Yellow line: https://commons.wikimedia.org/wiki/File:Byrne_35_diagram_4.png
 * Two right angles: https://commons.wikimedia.org/wiki/File:Byrne_47_two_right_angles.png

Other than those, I think it makes more sense to have specific angles for each page that match the diagram. The printed text does this for the most part, and it helps to avoid confusion about what each angle refers to in the problem.

The drop capitals I've scaled to 80px for consistency across pages.

But all of this is pretty arbitrary - it would be nice to have a consistent-looking book, and if you want to have a go, just get stuck in! Especially validating/tweaking already proofread pages if that's more manageable. I've been pretty flexible about line breaks - in the original book it's very hard to tell what's been indented, what's a new paragraph, whether the text is centered, etc. I've just tried to do something similar to the book, while making it relatively easy to follow the line of the argument. If you think something needs more line breaks, or fewer, just change it and play around.
