I’m sure this has been asked before, but I cannot find it…
Is it possible to set two arc lengths equal using relations? It seems that the only equal relation for arcs is radius.

Nope.
Vote on SPR 616783: Ability to create an equal length relation between a line and an edge, arc, or spline (curve).
Not using relations unfortunately, but you can add Arc Length dimensions & use the Link Value option.
Yea, I did that but the thing is then it is difficult to set the radius of the arcs to a nice number (or vice versa). In my case they are coradial and used to split the angle between two lines. I’d like to set the radius and tell the arcs to be the same length to give me my angle.
Add the chords as centerlines and make them equal.
Doh! You mean like this…
I was sitting here trying to decide if you couldn't just use straight lines of equal length (instead of arcs) when I noticed the thread had been updated. Looking at your sketch I think you could. Unles you need the arcs in there for something else.
I was trying to limit the number of clicks and cut down on clutter.
If you use the arc you don’t have to dimension and/or make equal the other two legs of the triangles.

Like that.
That got me thinking some more and I wondered if you could select the midpoint of an arc. I don't recall if I've ever needed to, but in fact you can. The angle dim's are driven, the construction line splits the angle between the other two. This might not work for every situation but it keeps things pretty simple.
