Complement of Theta.
In a right angled triangle, one of the angles is denoted theta. What is the symbol for the other angle? I have a vague feeling it's lower case sigma or phi but I can't find anything to comfirm or deny that.

I don't think there are any preferred symbols. People use whatever Greek letters they like best. α, β, γ are frequently used, for example.
In physics a glancing angle (the angle between an incident beam and the surface upon which it is incident) is often denoted by θ (theta).
